James Duff Billet machined pinion shims. Built to last will not break and leave you stranded as cast pinion shims will.

Improper pinion angle can lead to driveline vibration and premature u-joint & cv-joint failure. Not all 3 1/2″ lifts will require a pinion adjustment but going up to 5 1/2″ will result in a driveline angle that will need to be corrected. These 2 1/2″ wide steel shims bolt on to the bottom of your leaf packs with longer center pins included. To determine the proper amount we recommend taking measurements before and after installing your suspension lift. The optimum angle is 2°. For more measuring info, please call.

    These pinion shims worked great. I’ve got a 5.5” lift and the rear pinion angle was very bad. It caused bad vibration at speed, so much that the t-case shift knob looked like a blur because it was shaking so bad. After the shims the vibration is gone and the t-case shift knob is still as can be. This will extend the life of all drivetrain components and was a great investment.
