Carli 05-24 FORD F250/350 4X4 FORD PINION SHIM KIT, 2 DEGREE

When modifying the rear leaf springs (add-a-pack or Full Spring Pack) of the 2017+ Super Duty platform, there's a small chance you'll induce a driveline vibration around 70mph when under power from the rear driveline. These pinion shims will correct the angle to 4°-5°, ideal for our lifted applications. Although these will not be "required" on every truck, we've found the 4°-5° spec to be superior in our applications and these are FAR easier to install initially than correctively.
