Fishbone Offroad Universal 2.5in Leaf Spring Shim - Black

Made from black powder-coated steel, this Fishbone Offroad leaf spring shim is designed to fit 2.5-inch springs. Its primary job is to help correct your driveline angles, which can become problematic after lifting a vehicle. By adjusting these angles, you put less strain on your driveline components, especially the U-joints.

When you lift a truck or SUV, the angle of the driveshaft changes. If this angle is too steep, it can cause vibrations and premature wear on the U-joints. Installing these shims between the leaf spring and the axle housing tilts the axle slightly, bringing the driveshaft back into a more favorable angle. This not only helps prolong the life of your U-joints but can also lead to a smoother driving experience.

These shims are sold as a pair and are straightforward to install, making them a practical addition for off-road enthusiasts looking to address driveline issues after a suspension lift.
