QuadBoss 17-22 Kawasaki KAF400 Mule SX Upper Ball Joint Kit

Put an end to premature ball joint failure by upgrading from the O.E.M. aluminum joint to a heavy-duty steel joint. QuadBoss® Ball Joint Kits are also a great replacement for applications that would normally require you to buy an expensive A-arm or steering knuckle.

• Heavy-duty steel cases with a POM-M90 bearing cup isolate the ball end from the case for long life
• Ball joint kit is sold per A-arm and comes with snap ring and cotter pin
