Low Friction B/J Upper Screw-In + 1-1/2in

The Low Friction Ball Joint Upper Screw-In + 1-1/2in by ALLSTAR PERFORMANCE is a precision suspension component designed for serious street and competition builds where chassis geometry demands accuracy and repeatability. This upper ball joint is ideal for mechanics who specialize in front-end suspensions and need reliable performance under load.

Engineered to eliminate binding and reduce friction across the full range of motion, this screw-in ball joint is critical for maintaining consistent steering response and wheel alignment. Its low-friction bearing surfaces minimize stiction, enhancing handling precision. The threaded design allows for easy installation into existing control arm cavities without extensive modification.

This upper ball joint is particularly beneficial for applications in road racing, bracket racing, and high-performance street setups where OEM ball joints may not meet durability standards. Weighing 1.75 lbs, it provides a negligible unsprung weight penalty while delivering the stiffness and consistency needed for optimal road feel through the steering wheel.
