The Sixity XTA Axle is a severe-duty, OE-replacement ATV/UTV Constant Velocity axle (also known as a CV axle shaft or CV joint axle shaft) that dominates extreme trail and off-road terrain. With Sixity XTA axles, go beyond versatility to the ultimate in Sixity Axles offered at a fraction of the cost of OEM axles. The Sixity XTA axle defeats terrain vibration and harshness while ensuring riding agility and maximum torque. When it comes to 4-wheelers or side-by-sides, axles are one of the most important components, and depending on the rider, terrain, engine, and machine, they, like any other part, can fail. Before failure, there are signs and symptoms of a worn and damaged axle or CV joint to watch for including loud clicking noises when making a turn, a clunking sound when accelerating or decelerating, humming or growling noises, or a shudder or vibration when you accelerate. If this sounds all too familiar, it might be time to consider an axle replacement. Whether looking for a left or right CV axle, rear or front CV axle, rely on Sixity and our years of powersports expertise, along with our incredible selection, to help you find the exact severe-duty axle for your particular ATV/UTV vehicle application.
