Howe Racing 22420 GM K6145 Style Lower Ball Joint w/ Alum Cap
SKU-91722420
                        

Howe precision ball joints offer the precision of a spherical bearing with the misalignment range of a ball joint. They are easily rebuildable and adjustable. The alloy steel ball studs are process coated for low friction and long wear. You can feel the difference in smooth travel and easy steering effort.

These are press-in style and cross reference Speedway part #91720039 and MOOG #K6145.

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!

See Application tab for corresponding vehicle models. 

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.
