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 engineered for vehicles requiring adjustable lower suspension geometry and minimal rotational resistance. Designed for motorsports, street rods, and competition platforms, this screw-in ball joint delivers the precision articulation demanded by professional suspension tuners and fabricators who need repeatable, low-wear performance under dynamic load conditions.

Built with a 2.000 in/ft tapered design and low-friction bearing surfaces, the K772 screw assembly paired with the K6141 pin provides smooth, controlled suspension movement while the greasable construction enables extended service life through regular lubrication intervals. The 1-inch extended length geometry and 1.83-inch body at thread allow precise mounting depth adjustment, critical for maintaining correct camber, caster, and kingpin inclination across varied fabrication applications. Hardware is included, ensuring immediate installation without secondary fastener sourcing.

This ball joint suits frame-up restoration projects, independent front suspension (IFS) upgrades, and custom fabrication work where adjustability and serviceability are non-negotiable. Technicians prefer take-apart designs because they simplify inspection, bearing replacement, and preventive maintenance without component replacement. Compatibility varies by vehicle platform and suspension design; verify mounting diameter, thread pitch, and spindle/control arm bore specifications before ordering to ensure proper fit and alignment geometry.
