Low Friction B/J Screw K772 w/ K6141 Pin +1in

The Low Friction B/J Screw K772 w/ K6141 Pin +1in is a take-apart, greasable ball joint designed for vehicles that require adjustable lower suspension geometry and minimal rotational resistance. This product is ideal for motorsports, street rods, and competition platforms, delivering the precision articulation that professional suspension tuners and fabricators demand for low-wear performance under dynamic load conditions.

Engineered with a 2.000 in tapered design and low-friction bearing surfaces, the K772 screw assembly combined with the K6141 pin ensures smooth, controlled suspension movement. The greasable construction allows for extended service life through regular lubrication intervals, while the 1-inch extended length geometry enables precise mounting depth adjustment, which is critical for maintaining correct camber, caster, and kingpin inclination across various fabrication applications.

This ball joint is particularly beneficial for frame-up restoration projects, independent front suspension (IFS) upgrades, and custom fabrication work where adjustability and serviceability are essential. Technicians appreciate the take-apart design for simplifying inspection, bearing replacement, and preventive maintenance without the need for complete component replacement. Compatibility may vary by vehicle platform and suspension design; therefore, it is crucial to verify mounting diameter, thread pitch, and spindle/control arm specifications.
