Varying Strength Spring Shim

Color coded shims are located between the lower part of the spring and the spring seats. This is true of left and right, front and rear axles. The shims are NOT intended for adjusting vehicle height. They are used for compensating for differences in coil spring load groups.

If the differences in wheel load are too large, the arrangement of coil springs (same springs left/right) and shims at the bottom (same shims left/right) must be checked. Only coil springs and shims with the same color coding must be installed at the bottom of the left and right side of vehicle.

Due to varying trim variants (additional equipment), a maximum difference in wheel load of 88.2 lbs. (40 kg) from left to right is permitted per axle. This is partly the result of heavier components compared with standard equipment and partly results from additional components that are asymetrically arranged.
