Navitas vs. Alltrax AC Conversion Kits (2026): Performance, Price & Compatibility Compared

If you’re comparing Navitas vs. Alltrax AC conversion kits, the best choice depends on your golf cart’s existing drivetrain, desired performance, programming preferences, and budget.

Both manufacturers offer AC-drive solutions designed to replace compatible DC motor-and-controller systems. However, their kits differ in motor output, controller ratings, programming interfaces, vehicle applications, and included components.

For shoppers comparing currently listed options, three product families stand out:

• Navitas TAC2: A configurable AC conversion system with 440A or 600A controller options and application-specific motor choices.
• Alltrax AC1: A complete AC-drive conversion option, including selected 650A controller and 5.5kW motor packages.
• Navitas TAC3: A higher-output Navitas option with a 7.5kW motor and an 850A controller in selected compatible kits.

For example, Prime Golf Parts lists a Navitas TAC2 conversion kit for compatible EZGO TXT carts with a Curtis 1206HB controller at approximately 1,800–2,000, depending on configuration. A listed Alltrax AC1 650A/5.5kW EZGO TXT kit is approximately $1,780, while a Navitas TAC3 7.5kW/850A EZGO TXT package is listed around $2,500.

These are online product listings observed during this November 2026 review, not permanent price guarantees.

The important question isn’t simply which brand has the bigger amperage number. It’s which complete AC system is compatible with your cart and provides the performance you actually need.

This guide compares Navitas and Alltrax by price, motor power, programming, installation requirements, hill-climbing performance, battery compatibility, and real shopping scenarios.

Main consideration	Choose exact motor/controller configuration	Verify compatibility and programming needs	Higher price and greater system demands

Important: These ratings come from specific product families and configurations. They do not use a single standardized performance-test method. A 650A rating does not prove that an Alltrax kit accelerates faster than a 600A Navitas kit.

The most useful comparisons are based on compatible applications, included components, torque delivery, programming capability, battery requirements, and total installed cost.

You can compare the available golf cart AC conversion kits by make, model, motor output, and controller configuration before selecting a package.

What’s the Difference Between a Controller Upgrade and an AC Conversion Kit?

This is the first distinction to understand before spending money.

A controller upgrade changes the electronic device that manages motor power.

A DC-to-AC conversion kit changes the motor-drive architecture by replacing a compatible DC drivetrain with an AC motor and controller combination.

They are not the same purchase.

DC Controller Upgrade

A compatible DC controller upgrade may retain the original DC motor.

For example, a Navitas TSX or certain Alltrax SR/XCT controllers can be appropriate for particular DC motor systems.

Depending on the product and cart, a controller upgrade may affect:

• Acceleration response
• Available motor current
• Programmable operating limits
• Low-speed driving characteristics
• Regenerative braking on compatible systems

However, the existing motor remains a DC motor.

A higher-amperage DC controller does not automatically convert the cart to AC.

Complete AC Conversion

An AC conversion kit typically replaces the existing motor and controller with compatible AC components.

Depending on the application, the package may also include:

• AC motor
• AC motor controller
• Vehicle-specific harness or adapter
• Motor sensor cable
• Motor phase cables
• Mounting hardware
• Programming accessories
• Configuration-specific electrical components

An AC drivetrain can offer improved motor control, different efficiency characteristics, and greater flexibility for performance-oriented applications.

But real results depend on the battery, motor, controller settings, vehicle weight, gearing, and thermal limits.

Which Should You Buy?

If your existing DC motor is healthy and you only want better throttle response or moderate performance improvements, a compatible DC controller upgrade may be sufficient.

If your goal is a substantial drivetrain upgrade, a different motor performance profile, or a completely matched AC system, an AC conversion kit may be more appropriate.

Navitas AC Conversion Kits: Features, Options and Benefits

Navitas offers vehicle-specific performance systems for several popular golf cart platforms.

Its conversion-kit lineup includes different motor outputs, controller ratings, and application-specific harnesses.

The two major options considered here are TAC2 and TAC3.

Navitas TAC2: A Configurable AC Upgrade

Navitas TAC2 is a practical option for owners who want a matched AC motor/controller system with flexible programming.

For selected applications, configurations include:

• 440A controller with 4kW AC motor
• 600A controller with 5kW AC motor

However, not every Navitas vehicle application offers every combination.

A kit designed for an EZGO TXT with Curtis 1206HB electronics is not automatically compatible with another TXT generation or a Club Car.

For example, Prime Golf Parts offers a Navitas AC conversion kit for EZGO TXT with the applicable Curtis 1206HB replacement configuration.

Why Buyers Consider Navitas TAC2

Navitas TAC2 is attractive to shoppers who prioritize:

Adjustable driving behavior. Supported Navitas systems offer programming features that can help tailor acceleration, speed limits, and other drive characteristics.

Application-specific packages. Navitas publishes kits intended for particular controller and vehicle configurations.

Motor and controller matching. The conversion is designed around a compatible motor and controller rather than an independently selected controller.

Upgrade flexibility. Some owners prefer the ability to adjust certain settings after installation instead of committing to a single factory-style driving profile.

Navitas TAC2 Limitations

A TAC2 conversion is not universal.

The buyer must verify the correct existing controller, throttle interface, battery voltage, motor installation, and harness requirements.

Choosing a 600A option also does not guarantee better results than a 440A option if the battery or vehicle cannot support the extra demand.

Navitas TAC3: Higher-Output Performance Option

Navitas TAC3 provides a higher-output option within the brand’s lineup.

Prime Golf Parts lists selected TAC3 AC conversion packages with:

• 7.5kW AC motor
• 850A controller
• Model-specific kit configurations

Examples are listed for compatible EZGO TXT, Club Car, and Yamaha Drive/Drive2 applications.

A TAC3 system may appeal to buyers planning a more substantial performance build.

However, higher controller ratings also require careful evaluation of the battery pack, contactor, cables, thermal limits, driveline, brakes, and tires.

A more powerful package is not necessarily the best purchase for everyday neighborhood transportation.

For buyers seeking the higher-output configuration, compare the Navitas AC conversion kit options available for your exact vehicle.

Alltrax AC1 Conversion Kits: Features, Options and Benefits

Alltrax is established in golf cart controller upgrades, particularly with its SR and XCT product families.

However, for this comparison, the relevant product is the Alltrax AC1 AC conversion system, not the SR or XCT DC controller lines.

The AC1 package provides an alternative path for converting a compatible DC cart to an AC drivetrain.

Alltrax AC1 650A and 5.5kW Motor Kit

Prime Golf Parts lists an Alltrax EZGO TXT AC conversion kit containing an AC1 controller, 5.5kW motor, mounting components, and wiring hardware.

The published listing highlights:

• 650A controller rating
• 5.5kW motor
• USB programmability
• Compatible vehicle-specific connectors
• AC motor and controller included

The corresponding Alltrax AC1 documentation identifies a 650A one-minute phase-current rating and a lower continuous phase-current rating for the referenced AC1 controller.

These electrical ratings should not be treated as directly equivalent to a motor’s mechanical horsepower or battery draw.

Why Buyers Consider Alltrax AC1

Competitive package pricing. The listed EZGO TXT package is positioned close to lower-priced Navitas TAC2 configurations.

Complete AC conversion. The relevant package includes both the AC motor and the AC controller.

USB programming. Supported AC1 controllers offer configuration through Alltrax’s PC-based programming tools.

Motor output. The 5.5kW motor is a relevant specification for buyers comparing the included motor with other kits.

Vehicle-specific packages. Selected applications are offered with the necessary mounting and wiring components.

Alltrax AC1 Limitations

Although the package may fit a particular EZGO TXT or Club Car application, its controller and harness requirements must be matched to the actual vehicle.

Buyers should also check whether the desired programming interface suits their needs.

A USB-based programming approach may be convenient for owners comfortable using a computer, while others may prefer supported smartphone or on-the-fly adjustment options.

Neither approach is inherently better for every owner.

For example, the Alltrax 650A EZGO TXT DC-to-AC conversion kit is a direct product to compare against a compatible Navitas TXT package.

Navitas TAC2 vs. Alltrax AC1: Which Delivers Better Performance?

The controller rating is only part of the performance equation.

Both Navitas and Alltrax kits can improve performance over certain older DC configurations, but the size of that improvement is not universal.

Acceleration

Acceleration depends on how much torque reaches the wheels at a given vehicle speed.

Important factors include:

• Motor torque curve
• Controller output limits
• Battery current-delivery capability
• Gearing
• Tire size
• Vehicle weight
• Programming settings

A Navitas TAC2 600A system and an Alltrax AC1 650A system may behave differently even when installed in otherwise similar carts.

There is no reliable universal winner without comparable vehicle testing.

Hill-Climbing Performance

For golf carts used on steep properties, sustained power matters more than a short burst of peak controller current.

An AC conversion may improve hill-climbing behavior when the motor, gearing, and power delivery are suited to the application.

However, a high-current controller cannot compensate for an undersized battery or inappropriate gearing.

If your cart carries passengers, cargo, or larger wheels, calculate the expected vehicle load and select the system accordingly.

Top Speed

Neither brand guarantees a specific top speed based on the controller rating alone.

Maximum speed depends on:

• Motor RPM limits
• Tire diameter
• Final-drive ratio
• Programming
• Battery voltage
• Available motor power
• Vehicle conditions

A more powerful motor may maintain speed better under load without producing the highest unloaded speed.

Avoid selecting a kit solely because a retailer advertises an impressive mph figure.

Low-Speed Control

Low-speed drivability matters for navigating parking areas, golf courses, tight turns, and uneven ground.

A properly configured AC system can provide smooth throttle modulation.

However, the final result depends on the installed software settings and the condition of the associated components.

Regenerative Braking

Some AC conversion systems support regenerative braking, but the feature’s availability and behavior depend on the controller, motor, wiring, battery, and programming.

Regenerative braking is not a substitute for properly maintained mechanical brakes.

Verify the specific kit’s supported braking features instead of assuming all AC conversions operate identically.

Navitas vs. Alltrax AC Conversion Kit Prices in 2026

The cost of an AC conversion includes more than the advertised motor/controller package.

For this comparison, the following amounts reflect researched Prime Golf Parts listings in November 2026.

What Else Should You Budget For?

Depending on the vehicle and selected kit, additional costs may include:

• Professional installation
• Correctly rated battery cables
• Heavy-duty contactor or solenoid
• Battery testing or replacement
• Compatible wiring harnesses
• Electrical conversion components
• Mounting or hardware changes
• Programming and configuration
• Follow-up brake, steering, or tire servicing

Not every conversion requires replacing every supporting component.

A complete assessment prevents unnecessary purchases.

Is Navitas More Expensive Than Alltrax?

Not necessarily.

For the currently compared EZGO TXT packages, Alltrax AC1 has a slightly lower listed price than the base Navitas TAC2 range.

However, different Navitas motor options, alternative motor brands, promotions, or higher-output TAC3 configurations can change the comparison.

Compare the total package rather than only the brand name.

Which AC Conversion Kit Fits Your EZGO TXT?

EZGO TXT is a popular platform for performance upgrades.

But TXT vehicles have been produced with different electrical architectures, and an AC conversion kit must match the actual configuration.

Navitas EZGO TXT AC Conversion Kit

Prime Golf Parts lists a Navitas kit designed around the Curtis 1206HB controller application.

That is an important compatibility clue.

Before buying, verify the installed controller’s label, system voltage, and vehicle configuration.

Do not assume an RXV kit or a kit intended for another TXT controller will fit.

Alltrax EZGO TXT AC Conversion Kit

Prime Golf Parts lists the Alltrax AC1 650A/5.5kW EZGO TXT conversion package with motor, controller, mounting hardware, and wiring kit.

The fitment details still need to be checked against your current TXT generation.

A general marketing claim such as “fits TXT” should not override the exact electrical requirements in the installation documentation.

Which Should an EZGO TXT Owner Buy?

Choose a compatible Navitas TAC2 when accessible tuning and its specific kit configuration are priorities.

Consider Alltrax AC1 when the matching TXT package provides the motor, programming approach, and pricing you prefer.

Consider Navitas TAC3 when a higher-output system is warranted by your driving needs and the complete cart is properly prepared.

For additional options, browse EZGO golf cart AC conversion kits and filter by TXT and applicable specifications.

Which Kit Fits a Club Car DS, Precedent, Tempo or Onward?

Club Car compatibility requires particular attention to the original drive system.

The manufacturer used different electrical systems across the DS, Precedent, Tempo, and Onward families.

An IQ-equipped Club Car should not automatically be classified as an existing AC-drive cart.

Some original IQ systems use separately excited DC motors.

Navitas Club Car Conversion Options

Navitas offers application-specific AC conversion kits intended for selected IQ and APPS-related configurations.

Prime Golf Parts lists a Navitas AC conversion kit for Club Car IQ and APPS.

Compare the original Curtis controller model and connector arrangement before purchasing.

Alltrax Club Car Conversion Options

Prime Golf Parts also lists an Alltrax AC1 kit for selected Club Car Precedent, Tempo and Onward configurations.

This is not proof that the same package fits every DS or every Precedent.

The actual kit listing and system requirements must match the cart.

What About an Older Club Car DS?

For an older DS, determine whether the vehicle uses V-Glide, PowerDrive, IQ, or an aftermarket conversion.

A kit designed for one system may not work with another without substantial changes.

The most important purchasing rule is to identify the original controller and motor architecture before comparing AC kits.

Are Navitas and Alltrax AC Conversion Kits Available for Yamaha?

Navitas offers AC conversion packages for selected Yamaha Drive and Drive2 models, including configurations associated with compatible MORIC systems.

Prime Golf Parts lists Yamaha-specific Navitas conversion options in its AC conversion catalog.

However, the Alltrax AC1 kits discussed in this article are the specific EZGO TXT and Club Car packages identified in the store’s current comparison.

Do not assume an Alltrax kit for one manufacturer fits a Yamaha.

Yamaha owners should verify the exact Drive or Drive2 model, existing controller, voltage, and harness compatibility before selecting a conversion.

Explore Yamaha golf cart AC conversion kit options by filtering for the relevant model.

Do You Need a Battery Upgrade for an AC Conversion Kit?

Not automatically.

A compatible AC conversion system may operate with a suitable existing battery pack.

However, its performance depends on the battery’s ability to supply the required electrical power.

Lead-Acid Battery Considerations

An aging lead-acid battery pack may experience significant voltage sag under heavy acceleration or climbing loads.

A high-output controller cannot deliver its intended performance if the battery pack is unable to supply sufficient power.

Before buying an AC kit, evaluate battery condition rather than assuming the motor or controller is responsible for weak acceleration.

Lithium Battery Considerations

A compatible lithium battery pack may offer:

• Lower system weight in many applications
• More stable voltage under certain loads
• Different energy-storage options
• Reduced routine maintenance
• Battery-management protections

But lithium conversion does not automatically increase the motor’s rated horsepower or guarantee better performance.

The battery-management system (BMS) must support the drive system’s current and temperature requirements.

A 48V lithium pack with a large amp-hour capacity is not automatically suitable for every 600A, 650A, or 850A controller application.

Check discharge limits, motor-controller requirements, charger compatibility, and system architecture.

If a battery upgrade is part of the project, compare 48V and 72V golf cart lithium batteries for your vehicle.

Do You Need Heavy-Duty Solenoids and Battery Cables?

These components are important because they help deliver and control electrical power safely.

But a new kit does not automatically require every cable or contactor to be replaced.

The requirement depends on the manufacturer’s installation instructions, existing equipment, and selected power level.

Heavy-Duty Solenoids and Contactors

An electric golf cart contactor must have suitable:

• Coil voltage
• Continuous current rating
• Short-duration current capacity
• Terminal arrangement
• Electrical protection configuration
• Controller compatibility

Do not select a contactor solely because it has a “400A” or “600A” label.

Contactor ratings and controller motor-current ratings describe different components and should not be treated as interchangeable numbers.

Where an approved upgrade requires a higher-rated unit, explore heavy-duty golf cart solenoids.

Battery Cables

High-current electrical systems require cables and connectors with appropriate current capacity, insulation, routing, and terminal quality.

A larger cable can reduce resistive losses in some applications, but oversized cables are not a universal solution.

Use the kit manufacturer’s specifications to determine the correct cable size and connections.

Prime Golf Parts carries golf cart battery cable upgrade kits for selected performance applications.

Navitas vs. Alltrax: Which Is Better for Hills, Larger Tires and Passenger Loads?

Golf carts used for steep terrain or carrying extra weight place greater demands on the drivetrain.

For Hill Climbing

Compare sustained motor performance and controller thermal behavior, not only short-duration maximum current.

For a demanding route, the correct motor torque curve, vehicle gearing and battery system are critical.

For Lifted Golf Carts

Larger tires change the effective gearing of a golf cart.

They can reduce wheel torque at a given motor output and increase the work required during acceleration.

Before choosing a conversion package, identify the installed tire diameter and expected passenger load.

For Neighborhood Driving

Many owners do not need the highest available controller rating.

A properly matched lower-output package may offer the desired drivability without the expense and added demands of a more aggressive build.

For Heavily Loaded Carts

For utility use, commercial loads, or multi-passenger operation, check the vehicle’s original payload rating and drivetrain limitations.

An upgraded motor does not automatically increase the safe carrying capacity of the chassis or braking system.

Navitas vs. Alltrax Programming: Which Is Easier to Use?

Programming is one of the most meaningful differences between these product families.

Navitas Programming

Supported Navitas systems may provide app-based access for tuning and monitoring, as well as an on-the-fly programmer.

The available features depend on the controller generation and kit.

Potential adjustments include acceleration characteristics, speed-related settings, and other drive parameters.

Owners who regularly want to adjust driving behavior may appreciate this approach.

Alltrax Programming

The AC1 system offers a USB-based programming interface and supported Alltrax configuration tools.

This can suit owners or technicians who prefer a computer-based setup.

The exact functions depend on the product and firmware.

Which Interface Is Better?

Choose Navitas if the available programming ecosystem matches how you want to configure and monitor your vehicle.

Choose Alltrax if its USB-based controls and application-specific kit satisfy your needs.

Do not select either system solely on the assumption that every controller supports identical app features.

Safety note: Controller programming can affect acceleration, direction behavior, speed, and braking. Use approved settings and have safety-critical functions verified after installation.

Common AC Conversion Kit Buying Mistakes

Several mistakes can make an expensive drivetrain upgrade unsuitable.

Buying Only an AC Controller for a DC Motor

An AC controller cannot simply be installed as a direct replacement for an incompatible DC motor.

A full conversion requires a matched motor/controller system and the appropriate supporting parts.

Choosing by Amperage Alone

A 650A controller is not necessarily faster than a 600A controller.

Current limits, motor power, gearing, battery performance, and rating methods must all be considered.

Ignoring Original Controller Type

Two carts of the same brand and year may have different electrical configurations.

A kit intended to replace a Curtis 1206HB is not automatically compatible with every EZGO TXT.

Assuming Every 48V System Is Compatible

Some controllers, batteries, and charging systems have different voltage limits and electrical requirements.

Match the entire power system.

Forgetting Installation Components

A motor/controller package may require vehicle-specific harnessing, cables, mounting hardware, or additional electrical components.

Confirm exactly what is included.

Assuming a New Motor Fixes Every Performance Problem

Weak batteries, dragging brakes, oversized tires, poor connections, or damaged mechanical components can also cause poor performance.

Ignoring the Vehicle’s Safety Limits

A higher-output powertrain can increase the demands placed on braking, steering, tires, and drivetrain components.

Upgrades should not exceed the vehicle’s safe operating capability.

These are shopping recommendations, not guarantees of fitment or performance.

The final decision must be made using the product’s application specifications.

Is a Golf Cart AC Conversion Kit Worth the Money?

An AC conversion may be worth considering when you want meaningful changes to drivetrain performance rather than a minor repair.

It can be particularly attractive when:

• The existing DC motor requires replacement.
• A compatible AC system provides desired acceleration or torque characteristics.
• You want a matched motor/controller package.
• The cart is regularly used on demanding terrain.
• Programming features matter to your driving needs.
• You plan to keep the cart for several years.

However, it may not be the best investment if the original drivetrain operates well and the cart is used only occasionally on flat terrain.

A compatible controller upgrade or routine mechanical repair may offer better value in that situation.

The right purchasing decision depends on the actual performance problem and total project cost.

Final Verdict: Navitas or Alltrax?

For buyers comparing Navitas vs. Alltrax AC conversion kits in 2026, the right decision is based on the complete matched system.

Choose Navitas TAC2 when you want a compatible AC conversion package with supported programming options and flexible motor/controller configurations.

Choose Alltrax AC1 when a compatible 650A/5.5kW package meets your performance requirements and offers the pricing and programming approach you prefer.

Consider Navitas TAC3 when your cart and supporting electrical system justify a higher-output 7.5kW motor and 850A controller configuration.

If your existing DC motor is healthy and your needs are modest, a compatible DC controller upgrade may provide better value than a full conversion.

At Prime Golf Parts, you can compare Navitas AC conversion kits, golf cart DC-to-AC conversion kits, and motor and controller upgrade kits.

For a complete build, you can also review compatible heavy-duty golf cart solenoids, battery cable upgrade kits, and golf cart battery packages.
