Low Friction B/J Screw K772 w/ K6141 Pin +1/2in

The ALLSTAR PERFORMANCE Low Friction Ball Joint Screw K772 with K6141 Pin and +1/2in extended length is a take-apart, greasable lower control arm ball joint engineered for adjustability and serviceability in high-demand suspension applications. This screw-in design features a 2.000 in/ft taper and low-friction construction, making it the choice for fabricators and suspension specialists who demand precision fitment and extended component life.

The K772 is built around verified specifications: a 1.83-inch body at thread, +0.5 inch extended length for optimal geometry tuning, and a 2.000 in/ft taper that ensures repeatable preload and alignment. The greasable design allows field maintenance without component replacement, reducing downtime and total cost of ownership. All hardware is included for immediate installation. At 1.75 lbs, the compact assembly integrates into tight packaging scenarios while maintaining structural integrity under load cycling.

This ball joint serves fabricators, off-road builders, and suspension tuners working on custom frames where adjustability and repeatability are non-negotiable. The low-friction characteristic reduces steering feel dead-spot and allows for tighter geometry control—critical in performance driving, off-road recovery work, and competition chassis setups. The take-apart configuration means wear can be addressed without full assembly replacement, extending the service life of expensive control arm forgings.

ALLSTAR PERFORMANCE's screw-in ball joints are standard across fabrication shops and suspension specialty builders who prioritize bolt-in interchangeability and adjustable preload. The K772 with K6141 pin represents the mid-range taper specification suited to passenger and light-duty truck platforms where precision and serviceability justify the investment.
