QuadBoss 15-22 Honda TRX420 FA IRS Heavy-Duty Lower Ball Joint Kit

If you're hitting rough trails or carrying heavy loads on your Honda TRX500 FourTrax Foreman Rubicon, you know how important a solid front suspension is. This heavy-duty lower ball joint kit from QuadBoss is designed to replace the original aluminum joint, which can fail prematurely, especially under demanding use. It's a smart upgrade that helps keep your ATV handling predictably and reliably.

QuadBoss builds these ball joints with strong steel cases and a POM-M90 bearing cup. This setup isolates the ball end from the case, which is key to getting a long service life out of the joint. This kit is sold per A-arm, meaning you get one ball joint, a snap ring, and a cotter pin to get one side of your front suspension back in top shape. It’s a direct replacement that can save you from having to buy a whole new A-arm or steering knuckle if the original part wears out.
