Zone Offroad 2.5in x 4 Degree Shims (Pair)

With this purchase, you get a pair of Zone Offroad 2.5-inch wide, 4-degree caster shims. These shims are designed to help correct driveline angles, which is often necessary after lifting a vehicle. When you change the suspension height, the angle of your driveshaft can change, potentially leading to vibrations or premature wear. These shims are installed between the leaf springs and the axle to adjust the caster angle and bring the driveline back into a more acceptable operating range.

The 4-degree angle is a common adjustment needed for many suspension lift kits in the 2 to 4-inch range. They are made from a durable material to withstand the stresses of the suspension system. Installing these shims is a straightforward process for many DIYers, typically involving loosening the U-bolts and sliding the shim into place. It's a practical solution to address driveline vibrations that can arise from suspension modifications.
