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

The Low Friction Ball Joint Upper Screw-In + 1in from Allstar Performance is a precision suspension component designed for street rods, classic cars, and custom vehicle builds. This upper ball joint is essential for maintaining the critical pivot point between the upper control arm and steering knuckle, ensuring reliability during repetitive articulation and cornering loads.

Engineered to minimize binding and wear, this screw-in upper ball joint features a low-friction design that reduces internal drag, allowing for smoother articulation as the suspension compresses and extends. The screw-in installation method provides a secure mechanical lock with the control arm, simplifying installation and future service without the need for cotter pins.

This product is particularly beneficial for those restoring hot rods or upgrading classic muscle cars, as it allows for precise adjustments in caster and camber geometry. The +1 inch extension length is crucial for tuning independent front suspension setups, where minor changes can significantly impact wheel alignment and handling characteristics.
