AFCO 20039LF Low Friction GM Lower Ball Joint
71-96 Buick, 70-02 Chevy, 73-02 GMC, 71-92 Oldsmobile, 70-89 Pontiac, Hobby Stock, Steel
- These ball joints are designed with 2 ft. lbs. of resistance, which is the force required to move the stud of the ball joint
- The low friction allow the suspension to give rather than allowing the tire to bounce over rough surfaces
- Will fit several GM car and truck applications (see list)
- Are precision machined to tight tolerances, providing consistent resistance throughout the travel of the ball joint to deliver consistent performance
- Engineered to free the up suspension for more consistent, repeatable chassis tuning
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.
