Installed the G-Boost severe duty belt on my G16 and wow what a difference! No slipping under load and the cart feels way snappier now. Definitely worth every penny.

Good heavy-duty belt, fits my G22 perfectly. Took a bit of stretching to get it over the clutch but now it grips tight. Big upgrade over the stock belt!

How much break-in do these belts need? Mine was a little stiff first few rides but after some use it’s super smooth on my G11 cart.

Heavy-duty for sure. I use my 2002 G22 for hauling gear and this G-Boost belt handles the extra weight without a single slip. Shipping was fast too!

Installed the G-Boost Severe Duty Drive Belt on my Yamaha G16, and it’s been flawless! No slipping, super smooth engagement. Easily one of the best replacement belts for Yamaha gas golf carts. Fast shipping too, arrived two days early! Definitely recommend for anyone tired of OEM belts stretching too fast.

Belt quality seems ok. Maybe i got a bad one? My G28 cart chirps a bit on launch now. Not sure if the severe duty drive belt needs a break-in period? Gonna give it another few rides and see. Shipped super fast tho and price was better here than anywhere else.

Absolute beast of a belt. Perfect fit for my Yamaha G11. I’m running oversized tires and needed a high-performance drive belt for golf carts that wouldn’t slip under load. This one hooks up every time. Quick delivery, solid packaging, and killer price point.
