This TAC3 850A + 7.5kW Navitas AC conversion kit completely transformed my EZGO TXT 72V. The torque increase is crazy—feels like a brand-new cart. Install was smooth, and the included Navitas controller app is a game-changer for on-the-fly adjustments. Easily outperforms the old 1206HB controller. Highly recommend for anyone upgrading to AC drive.

Shipping was super fast—got it in 2 days. The performance boost on my EZGO TXT 48V is noticeable right away. Acceleration and hill-climb torque are way better. Only knocked off a star because the instructions could’ve been clearer. Still, a great AC motor upgrade kit.
Brad T. –
After replacing my stock 1206HB controller with this Navitas 7.5kW conversion kit, I’m seeing better speed, range, and control. Regenerative braking is smooth, and the TAC3 850A controller handles power delivery like a beast. Worth every penny.
Linda R. –
I was excited to get this conversion kit, but UPS misplaced my package. Prime Golf Parts was quick to send a replacement though, which I appreciate. The kit runs well, but for the price, I expected a bit more detailed support documentation. Might be tricky for first-timers.
Chris V. –
This AC kit brought my 2015 EZGO TXT to life. The Navitas 7.5kW motor runs quiet and cool, and I love the smartphone tuning features via Bluetooth. Plug-and-play install with no surprises. Solid replacement for the outdated 1206HB Curtis controller.
Josh L. –
Is it normal for this kit to pull more amps than the stock setup? Performance is wild—cart launches like it’s on nitro. Just wondering if this affects battery life long-term. Anyone else see this with the TAC3 850A controller?
Steve N. –
Best price I could find online for the TAC3 850A Navitas conversion. Delivered fast, and everything fit my 48V EZGO like a glove. Smooth throttle response, and top speed increased by at least 7 MPH. The torque curve is totally different—way better.
Mike S. –
Torque on demand—this is what an EZGO should feel like! My 72V TXT now climbs hills like nothing. Installation was pretty simple with basic tools. Replacing the old 1206HB controller was totally worth it for the boost and battery efficiency with AC.
Greg F. –
Everything works great, but be warned—this kit really brings out weak spots in your wiring and battery setup. Once I upgraded my cables, it ran smooth. Navitas 7.5kW motor + TAC3 850A controller is a powerful combo.
Jason P. –
Can’t believe how much better my EZGO TXT performs with this Navitas 7.5kW AC kit. Smoother acceleration, better regen braking, and less heat on long rides. I was hesitant about replacing the 1206HB controller, but now I’d never go back.
Brian K. –
Still trying to dial in the throttle response. It’s fast—maybe too fast. Great kit, but the learning curve on tuning the Navitas controller caught me off guard. Tech support was helpful though.
Jake F. –
I race custom carts and this AC motor + TAC3 controller combo is a beast. Best acceleration I’ve felt in this price range. Setup wasn’t plug-and-play for my build, but nothing a few adjustments couldn’t fix.
Laura D. –
Perfect match for my 48V EZGO TXT. I wanted more range and smoother control for campgrounds, and this delivered. Installation took under 4 hours and the Bluetooth tuning via the Navitas app is very intuitive.
Kyle S. –
Speed went from 19 MPH to 32 MPH on my TXT after installing this! Throttle is super responsive and the torque makes off-roading way more fun. Navitas really nailed it with this setup.
Tony G. –
Anyone else notice a slight delay at low speeds? It’s not a dealbreaker, but I’m curious if that’s normal for the TAC3 850A. Still, performance is awesome once you’re rolling. Love the quiet hum of the AC motor too.
Derek L. –
Crazy power boost and better efficiency on my lithium-powered TXT 72V. Replacing my 1206HB Curtis controller was the best move. The regen braking alone makes this worth it—saves my brakes big time on trails.
Blake R. –
Prime Golf Parts had the best deal I could find and shipped same day. Kit came with everything I needed. Only complaint is I had to download the wiring diagram separately—should’ve been printed in the box.
Matt B. –
Blown away. I use my EZGO for hauling gear around my property and the torque improvement is insane. Pulls loads like a utility cart now. TAC3 850A + Navitas 7.5kW is a killer combo for anyone doing real work with their golf cart.
Jake W. –
Replaced my stock 1206HB controller with this Navitas TAC3 850A and 7.5kW motor—game changer. My EZGO TXT 72V is way faster, smoother, and stronger uphill. Definitely the best upgrade I’ve done.
Mark J. –
Does this kit work with older TXT carts from early 2000s? I’ve upgraded my batteries to 48V lithium and want to boost performance. Want to make sure throttle wiring matches.
Peter P. –
Install went smooth and performance is 🔥. Throttle response is tight, and I noticed immediate torque gains. This Navitas AC conversion kit really wakes up an EZGO TXT. Shipped quickly too!
Dan B. –
Good power but had a few issues pairing the TAC3 controller with my existing wiring. Customer service helped me sort it out. Cart definitely feels stronger now than with the old 1206HB.
Kate F. –
My EZGO TXT was struggling before this upgrade. Now with the 7.5kW motor and 850A controller, I’m hitting over 30 MPH on flat ground. Plus, regenerative braking is a nice touch.
Tony L. –
One of the best Navitas kits out there. The AC motor is smooth, quiet, and efficient. Just double-check compatibility if you’re running a non-OEM battery pack. Otherwise, solid upgrade.
Justin E. –
Big jump in speed and hill power after installing this. Replaced the stock 1206HB controller with no issues. Would love to see a printed install guide in the box, but the online one worked fine.
Adam H. –
Best price online for the 7.5kW Navitas AC conversion kit. Super fast delivery too. Got it on my 2018 EZGO TXT and it runs like a dream—quieter, faster, better throttle feel.
Cody S. –
Is anyone else having trouble connecting to the TAC3 controller via Bluetooth? The app is helpful, but mine’s not picking up the device. Performance is good though. Speed and torque are there.
Bob D. –
My 48V EZGO went from sluggish to sporty. This high-performance AC conversion kit from Navitas is no joke. Controller is responsive, and programming it was super easy using the app.
Ethan T. –
Just finished the swap and loving it so far. The TAC3 850A controller really changed how the cart feels. Wish I had done this sooner instead of rebuilding the old 1206HB again.
Kyle A. –
Best upgrade for an EZGO TXT hands down. The 7.5kW motor gives it serious pull. Replacing the 1206HB with the TAC3 took a little time but well worth it for the results.
