AFCO Ball Joint Low-Friction K3136 Bolt-In Upper 20032 Extended - 20032-1LFAFCOs low friction ball joints are designed with 2 ft. lbs. of resistance, the force required to move the stud of the ball joint. Compare this with standard replacement joints, with up to 50 ft. lbs. of resistance. Only 2 ft. lbs. of resistance and less bind = lower lap times. Improves weight transfer. Frees up suspension for more consistent, repeatable chassis tuning. Precision machined to tight tolerances, providing consistent resistance throughout
