Q & A

What's in the Box

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!

  1. This ball joint uses the Ford taper found on Mustang II/Pinto spindles. Common on IMCA Modifieds.
  2. This ball joint will NOT fit the stock taper in a 1963-71 GM truck spindle. To use this with GM-type spindles the upper taper must be reamed with reamer 910-89411.

Will NOT fit stock GM pickup upper A-frame or spindle taper.

Application

Fits:
  • Mastersbilt, GRT, American Made, Swartz, Bernheisel, Rocket, Howe, Shaw, Bullitt, Rayburn, Harris

Notes

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. 

  • Precision machined to tight tolerances, providing consistent resistance throughout the travel of the ball joint to deliver consistent performance
  • Improves weight transfer
  • Frees up suspension for more consistent, repeatable chassis tuning
  • Removes suspension rigidity and allows shock and spring to have more precise wheel control
  • Adjustments are controlled more effectively by the shock and spring instead of the tire which improves traction
  • Provides more accurate set-ups during vehicle scaling
  • Meets or exceeds standard ball joint strength
  • Stock appearing
  • Lower input steering efforts and faster steering wheel return

Howe Precision Ball Joints offer the precision of a spherical bearing with the misalignment range of a ball joint. Their rugged steel housings will withstand impacts that can destroy other ball joints. Plus, even if you manage to damage the joint, they are fully rebuildable. The alloy steel ball studs are process coated for low friction and long wear. You will feel the difference in smooth travel and easy steering effort.
