UTV U-Joints

Shop UTV U-Joint Kits for Your Prop Shaft and Drive Shaft

A worn U-joint on your front prop shaft or drive shaft shows up fast. You get vibration at speed, clunking under load, or a driveline that flat-out quits mid-ride. Good U joints are built around needle bearings pressed into a steel cap assembly, and the quality of those materials separates a joint that lasts a season from one that lasts a few years. We stock U joint kits for Polaris, Can-Am, and other popular UTV platforms so you can replace what's bad and get back on the trail without hunting down the right part from five different places.

When you're replacing U-joints, it pays to check the full driveshaft while you're in there. A worn carrier bearing on the same prop shaft can cause a similar vibration, so inspect the carrier bearing whenever you replace the U-joints. A bad joint often means the surrounding components have taken wear too. Our U-joint kits are designed to fit your vehicle's stock prop shaft dimensions, and many are upgrades over OEM, using chromoly steel and tighter-tolerance needle bearings to handle more torque and resist water and debris better than the factory. Pick the kit that matches your machine, order today, and most orders ship the same day from our warehouse.

FAQ 

What causes UTV U joints to go bad?

Water, mud, and grease loss are the main culprits. Once the grease breaks down or contaminants get into the needle bearings, the bearing cups wear fast. Hard use on rough terrain speeds that up, especially on the front prop shaft, where the joint angles are more severe.

How do I know if my UTV U joint needs to be replaced?

A clicking or clunking noise during acceleration or deceleration is a common sign. You may also feel vibration through the driveshaft at certain speeds. If the joint has visible rust, play, or dry bearings when you spin it by hand, it's time to replace it.

Are UTV U joint kits a direct fit for stock prop shafts?

Most U-joint kits are designed to match OEM dimensions, so they drop into your existing front prop shaft or drive shaft without modification. Always verify the kit matches your machine's year, make, and model before ordering.

What's the difference between a U joint and a CV joint on a UTV?

A U joint uses needle bearings in a cross-and-cap design to transfer torque through an angle. A CV joint uses a ball-and-socket design that keeps rotational speed constant through greater operating angles. Prop shafts commonly use U joints, while axles typically run CV joints.

Do UTV U joints need to be greased?

Some upgraded U-joint kits include grease fittings and benefit from periodic greasing to extend bearing life. Others are sealed from the factory and require no maintenance until they're replaced. Check the product specs for the kit you're ordering to know which type you're getting.

Can I replace UTV U joints myself?

Yes. Most U-joint swaps are a straightforward job with basic hand tools. You'll press the old bearing caps out and the new ones in, which you can do with a bench vise if you don't have a press. A short video search will walk you through the process for your specific driveshaft setup.

Which UTV brands do these U-joint kits fit?

We carry U-joint kits that fit Polaris RZR, Can-Am, and other popular ATV and UTV platforms. Use the fitment filter when you shop to match the right kit to your vehicle's year and model.
