QA1 builds the Ultimate Ball Joint for a wide range of racing and performance suspension applications. This patented, self-lubricating design is exclusive to QA1 and is 100 percent owner rebuildable, with all internal parts replaceable at economical prices. Multiple stud lengths allow easy geometry changes, and infinite preload adjustment lets breakaway torque be set as low as 0 ft-lbs for smooth, bind-free operation. Precision tolerance ball-to-race conformity distributes load evenly for strong wear resistance, and a precision-ground 52100 bearing steel race delivers long life and smooth movement. The ball joint can be adjusted without removing it from the vehicle, which makes roll center tuning simple.
