Tuff Country 4 Degree Axle Shims 2in Wide w/ 3/8in Center Pins Pair

If you've recently installed a lift kit on your truck or SUV and are noticing some annoying rear-end vibrations, these Tuff Country axle shims are likely what you need. They're designed to be installed between your rear leaf springs and the axle, working to change the angle of your rear differential. This adjustment is key to eliminating or at least significantly lessening those unwanted vibrations.

These shims feature a 4-degree taper, which is a common angle used to correct pinion angle issues that often arise after lifting a vehicle. The 2-inch width and 3/8-inch center pins are standard sizes that fit the rear end of most trucks and SUVs that use leaf springs. By rotating the rear axle slightly, these well-built shims help bring your driveline angles back into a more acceptable range, smoothing out your ride.
