  • Knurled ball joints required when replacing knurled ball joints that have enlarged the axle end forging bores
  • Non-Knurled ball joints recommended for replacing non-knurled ball joints
  • Due to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
  • Use of the improper ball joint style for the axle housing voids our lifetime warranty. It is up to the installer to verify the proper ball joint style is being used.
  • Compatible with RCV axle shafts
  • Rebuild Kits and Replacement Parts Available Here.

Limited Lifetime Warranty:

  • For the original purchaser, this warranty covers defects in materials or workmanship of the ball joint for the lifetime of the joint. Ball Joints are wear items and normal wear of the ball joint is not subject to this Limited Lifetime Warranty. The wear items of the ball joint will periodically need to be replaced once the adjustment in the joint is used up and are available separately as a ball joint rebuild kit. Length of time between rebuilds is subject to the use and build of the vehicle.
