AFCO 20039 K6145 Standard GM Lower Ball Joint
SKU-10620039
                        

Not all ball joint are created equal.  That's why AFCO uses the best components from the top manufacturers.  There are many different design characteristics and manufacturing processes that account for the quality and performance of ball joints.  These joints will give you the AFCO advantage!

AFCO 20039LF Low Friction GM Lower Ball Joint
SKU-10620039LF
                        

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.
