UTVs – especially sport and recreational UTVs – put a lot of strain on the axles. Different types of terrain cause varying amounts of strain. For example, heavy mud can put a lot of stress on the axles while they’re turning. And riding on rocky terrain can sometimes result in sudden impact that the axle simply can’t handle.
For the most part, axles are pretty well built for the task, but they can wear out and break (particularly at the CV joints). On some machines, the axles themselves may even bend slightly if they take too much abuse. We carry excellent aftermarket products that will replace OEM axles, getting you back out riding again.
The CV boots protect the mechanical components of the joints as they move. The boots keep dirt out and the grease in. However, the rubber can wear out and create holes, leading to premature joint wear. If you notice that your CV boots have a tear, all you need to do is replace the boot itself. We have several universal boot replacement kits that are perfect for this problem, and they can save you from a much more expensive replacement down the road by properly protecting the CV joints.
Aside from axles, this page is also the starting point for other related UTV axle parts, including rear axle bearings and wheel spacers. Check out our selection now!

High quality! Better than the original. Easy to install with the right tools. Sorry guys, you need more than a screwdriver and crescent wrench.

These have performed extremely well. I was breaking factory half shafts 1-2 times a year. I switched to another brand, and those did well, but the boots would tear easy and grease would fly everywhere. They have surprised me how well they hold up. I am very hard on equipment, I push the machine to the limit. I have Tusk axles front and back of unit. The have held up well. I had to make small change to gear box to keep outer casing from rubbing, but that's it. I am still amazed by the low price for them.
