Z Height Adjustment

WARNING: This page is about a different car, the 2003 GMC Jimmy and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

For vehicles equipped with a torsion bar suspension, turn the bolt (1) that contacts the torsion arm as needed. One revolution of the bolt (1) into the nut, increases the Z height by approximately 6.0 mm (0.2 in).

For vehicles without torsion bars replace damaged or worn components as necessary.
If these measurements are out of specifications, inspect for the following conditions:
- Sagging rear suspension. Refer to Coil Spring Replacement in REAR SUSPENSION .
- Collision damage.
