QuadBoss Heavy-Duty Ball Joint Kit

This heavy-duty steel ball joint kit from QuadBoss is built to last. It replaces the original aluminum joint on your vehicle, which can fail prematurely, especially under tougher conditions. This upgrade uses a strong steel case to handle more stress than the stock part.

Inside the steel case, a POM-M90 bearing cup separates the ball end from the housing. This design helps isolate the ball from impacts and wear, contributing to a longer service life. This kit is a smart replacement if your A-arm or steering knuckle would otherwise need to be replaced, saving you money on a more extensive repair.

Each kit is sold individually for one A-arm and includes the necessary snap ring and cotter pin for installation.
