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.
These are NOT a direct fit in the stock pickup A-frames. Used on IMCA cars to raise roll center (raised pivot point).
- These ball joint use a 1973-95 GM Truck taper, but they have a longer (taller) stud than the stock GM part. The taller stud changes the pivot point due to its length, which in turn raises the car's roll center. Very common ball joint on IMCA Modifieds.
- Lower ball joint fits most stut cars, 1971-1976 Impala and most wide-type dirt cars. Press-In.
- Fits most popular racing and passenger car spindles.
