Suspension Strut / Shock Absorber: Adjustments

Rear Strut Stabilizer Block Adjustment

The rear axle spring strut is equipped with a threaded sleeve and an adjustment nut (no.1) for height adjustments. In addition, the stabilizer block (no.3) (support for stabilizer mount) is attached to the thread. The height of the stabilizer block is adjustable and it is equipped with a lock nut (no.2).

The stabilizer block must only be adjusted for racing purposes. The purpose of adjustment is to ensure that sufficient space is still available for the stabilizer mount if the vehicle height is changed (only for racing) and that the stabilizer mount can be installed without stress. With the vehicle height specified for road use the stabilizer block does not need to be adjusted.

The stabilizer block is also correctly adjusted for replacement shock absorbers (dimensions B and C).

If lock nut no.2 is unscrewed (normally not necessary), a normal hook wrench is required. The tightening torque is 100 Nm (73.7 ft. lb.). Using a normal hook wrench, it is only possible to apply about 50 Nm (36.9 ft. lb.). In this case, an extension (tube) must be inserted onto the hook wrench.

Higher torque values up to about 200 Nm (147.5 ft. lb.) will cause no damage whatsoever to the thread.

Dimension A = Pre-setting for production (182 ± 1 mm). For the specified vehicle height, the actual dimension may be different. If the shock absorber is replaced, the actual dimension must be transferred to the new part.
Dimension B = 147.5 ± 0.5 mm
Dimension C = 110.5 degrees
