1. For vehicles equipped with a torsion bar suspension, turn the bolt (1) that contacts the torsion arm clockwise to raise, and counterclockwise to
lower, the height adjustment. One revolution of the bolt into the nut increases the Z height by approximately 6 mm (0.2 in).
2. For vehicles without torsion bars, replace damaged or worn components as necessary.
D Height Measurement
The D height dimension measurement determines the proper rear end ride height. No adjustment procedure is available. Repair may require replacement
of suspension components.

2. Suddenly remove your hands.
3. Allow the vehicle to settle into position.
4. Repeat the jouncing operation 2 more times.
5. The D height is obtained by measuring the distance between the edge of the jounce cup along the jounce bumper center line and the jounce pad on
the rear axle.
6. The true D height dimension number is the average of the high and the low measurements. Refer to Trim Height Specifications (See:
