1. Raise the vehicle to a safe and comfortable working height. Use jack stands to support the vehicle with the suspension hanging freely. 2. Support the axle and remove the bump stops, leaf springs, shocks and tail pipes. Refer to the factory service manual for proper disassemble procedures. Keep the factory upper shock bolts, bump stop bolts, U-bolts, and front leaf spring mount and bolts. 3. One more thing needs to be removed before starting the assembly; it’s the pinion snubber and mount.

6. Install the large end of the lower bar (the long one) into the factory spring mount using the factory hardware. Do not over tighten this bolt; it should be snug. The bar is offset to the inside of the car for wheel and tire clearance. 7. This bushing is polyurethane and is lubricated at the factory with lithium grease, additional lubrication is not needed. Future lubrication can be done using any non-petroleum based lubricant. 8. Bolt the bar and mount back onto the car using the factory hardware. 9.

Upper Bar Installation Jig • • • • • • • • • • • This jig has been supplied to aid in the installation of the upper 4 link bar. It can be temporarily used to properly align, locate and weld the tabs onto the axle. It will also ensure that the mounting bolts are parallel to the ground. Follow the diagram below to set the jig to the same length as the upper bar, use the 3/8” x 3/4” bolt and nuts to set the length. Position the axle at ride height. Center the axle left to right between the quarter panels.

15. How do you set the pinion angle? On a singlepiece shaft you want to set it up where a line drawn through the center of the engine crankshaft or output shaft of the transmission and a line drawn through the center of the pinion are parallel to each other but not the same line. A simple way to do this is to place a digital angle finder or dial level on the front face of the lower engine pulley or harmonic balancer.

16. One helpful trick to help maintain ride height and pinion angle while adjusting is to tack weld a spacer between the axle and the outside of the frame as shown in the picture. This spacer should be 8 3/8” tall giving the Shockwave an eye-to-eye measurement of 14 1/2" to 15”. 17. After double-checking pinion angle, ride height, and axle center the tabs can be tack welded. Remove the bar to avoid frying the bushing and finish welding the tabs to the axle. 18.
