Erase Belt Slip, Unleash Raw Power: Ultimax Drive Belts

If you’ve ever mashed the throttle to climb a steep dune, haul a heavy load, or pull your buddy out of a mud hole, only to hear your engine scream while your tires barely move, you know the absolute frustration of belt slip. Sluggish factory belts stretch, glaze over, and generate massive amounts of friction under load, robbing your side-by-side of horsepower and eventually leaving you stranded with a shredded mess. Put an end to lagging acceleration and upgrade to the gold standard of CVT performance with Ultimax Belts!

Right here at Side By Side Stuff, we stock an essential inventory of Ultimax’s advanced drive belts, engineered specifically to handle the brutal torque of modern powersports machines. Built by Timken, a global leader in high-performance manufacturing, these lines feature the iconic Ultimax XP series, a severe-duty belt constructed from an advanced fiber-loaded rubber compound and reinforced with ultra-strong aramid cords. Designed to endure extreme thermal tension, Ultimax belts run cooler, grip the clutches with zero hesitation, and maintain consistent RPMs throughout your entire powerband.

Ultimax focuses on unmatched dimensional consistency, meaning every single belt is precision-crafted to match your machine's exact pulley geometry for smoother backshifting and reduced wear on your clutches. Stop riding on borrowed time with a worn-out stock setup, drop in a premium, race-proven belt, maximize your torque transfer, and tackle the trails knowing your drivetrain is built to endure the abuse.
