Great stock replacement

February 27, 2010
Affordable, quality replacement part for hobby/street stocks. The specs don't mention that the lower joint is .020 over sized. While oversize is standard in most aftermarket replacement lines (to accommodate sloppy press fits on 25 yr + vehicles), it is usually noted. This was not noted but is over size. If you have stock joints that have never been out of the A arm you'll need to machine or die grind a bit of the arm material prior to installing the joint.
Pros:
  • Great stock replacement
Yes, I recommend this product.

Howe Racing 22420 GM K6145 Style Lower Ball Joint w/ Alum Cap
(Part #91722420)

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.

AFCO 20039 K6145 Standard GM Lower Ball Joint
(Part #10620039)
                        

Not all ball joint are created equal.  Thats 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
(Part #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.
