Low Friction B/J Upper Screw-In Std Height

The ALLSTAR PERFORMANCE Low Friction Ball Joint Upper Screw-In Standard Height (ALL 56010) is a greasable upper ball joint engineered for suspension geometry precision and extended service life. This screw-in style upper ball joint features a low-friction design paired with a 1.500-inch-per-foot taper, making it suitable for high-demand automotive applications where consistent alignment and reduced binding are critical to handling performance and tire wear control.

The screw-in mounting configuration provides straightforward installation and removal without requiring specialized pressing equipment, reducing downtime during maintenance or suspension rebuild cycles. The greasable design allows for routine lubrication to minimize friction and wear on the ball stud, extending component longevity under racing or high-mileage conditions. All necessary hardware is included, eliminating the need to source fasteners separately. The standard height specification fits OEM and common aftermarket control arm configurations, making it a practical choice for chassis builders and suspension technicians working across multiple platforms.

This upper ball joint is ideal for street-performance vehicles, circle-track race cars, and off-road builds where suspension compliance and steering feel matter. Buyers restoring independent front suspension systems or upgrading from worn OEM joints benefit from the low-friction geometry that reduces kickback through the steering column and improves feedback to the driver. ALLSTAR PERFORMANCE components are recognized across automotive competition and restoration communities for consistent quality and precise manufacturing tolerances.

When replacing upper ball joints, proper vertical load alignment and preload control are essential to suspension geometry. The standard height of this unit ensures compatibility with common control arm designs while the 1.500-inch taper maintains the angular relationship necessary for correct camber and caster settings. Whether performing a full front-end rebuild or addressing steering play and suspension noise, this screw-in upper ball joint provides the precision fit and durability expected from a dedicated automotive suspension manufacturer.
