AFCO 20039LF Details

AFCO 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 as high as 50 ft. lbs. of resistance. A difference you can feel!

It is critical to handling that suspension components be as free as possible to move. Low friction ball joints allow the suspension to give rather than allowing the tire to bounce over rough surfaces. Low tire pressures magnify the need to minimize friction in the suspension.

See Application tab for corresponding vehicle models.
