Engineered from the ground up to be the highest-quality, most reliable and toughest CV axles on the market, TrakMotive OE-replacement CV axles will withstand the most rigorous conditions and combat-rough terrain — water, mud and sand. Each application is torture-tested to failure to ensure maximum durability. TrakMotive axles handle up to 20 percent more torque than OEM axles and feature precision-machined, heat-treated solid chrome-steel center shafts, cages, races and ball bearings. The induction-heat-treated joints are constructed to work at varying angles and constant rotational speeds without friction or play, and they’re packed with high-performance moly grease providing better metal adhesion and resistance to high shock loads. Precision-rolled splines and threads improve fitment and wear, while high-quality neoprene dust boots secured with stainless-steel clamps allow for greater flexibility and increased heat and chemical resistance. Every axle comes fully assembled with all necessary hardware for easy installation without modification and is backed by a one-year limited warranty. TrakMotive offers industry-leading ATV, UTV and side-by-side application coverage with fitments available for all major manufacturers. Experience the TrakMotive advantage today!

For many UTV racers, making it through an entire race with a stock gearbox and front differential is a challenge. Mass-produced stock gears crack when subjected to extreme racing conditions. Certain manufacturers assemble their gearboxes with poor-quality bearings that also can’t stand up to race conditions. Factory-assembled gearboxes also neglect critical adjustments to the gear stacks, which may cause the gears to lose their optimal mesh, thus accelerating wear that can lead to complete failure. Weddle race prep takes extra steps to get your stock UTV gearbox race-ready. First, gear teeth are hand-ground to relieve areas prone to stress fractures. Next the gears are shot-peened, making them more durable by relieving the surface tension that remains after initial manufacturing. All components are then REM Superfinished to remove surface imperfections. This process minimizes friction and heat, and it improves the longevity of shift performance by reducing wear on the gear teeth. REM also prevents microscopic ""wear"" material from shedding into the oil where it could increase wear on critical bearings. Stock bearings are replaced with high-quality upgrades designed to handle extreme race conditions. Finally, the gearbox is professionally assembled with all the critical adjustments required to handle the roughest terrain. Weddle Sportsman prep is an economical upgrade for your factory gearbox. All gears are REM Superfinished to reduce friction and heat, and to promote longer gear life. Poor-quality factory bearings are replaced with high-quality upgrades.
