Product Details
If you're tackling suspension repairs on your ATV, replacing a worn lower ball joint is a common task. This QuadBoss Lower Ball Joint Kit is built to last, offering a significant upgrade over stock aluminum joints. It's designed to fit a range of popular ATVs, including models like the Polaris Outlaw 450 MXR, Can-Am DS 250, and Polaris Outlaw 525 IRS.
Instead of just a basic replacement, this kit uses heavy-duty steel cases. Inside, a POM-M90 bearing cup isolates the ball end from the case. This design helps prevent premature wear and failure, which can save you from having to replace entire A-arms or steering knuckles down the road. The kit is sold per A-arm, meaning you get one ball joint and the necessary hardware like a snap ring and cotter pin to get the job done right.
