Engineered for professional racing applications, the QA1 Ultimate Ball Joint Component Kit (MPN 1210-523) features a patented, 100% owner-rebuildable design that allows for precise suspension tuning without removing the housing from the vehicle. These self-lubricating ball joints are designed for extreme durability and smooth, bind-free operation under heavy loads.

The kit utilizes a precision-ground 52100 bearing steel race for exceptional wear resistance and even load distribution. With infinite preload adjustment, users can set breakaway torque as low as 0 ft-lb, ensuring the suspension remains responsive and free of mechanical stiction. This 1.625in component kit is ideal for racers needing to fine-tune roll centers and maintain consistent geometry through every corner.
