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 leaf springs, shocks, bump stops, pinion snubber and tail pipes. Refer to the factory service manual for proper disassemble procedures. 3. The parking brake brackets will be in the way of the 4 link and must be removed. Loosen the parking brake adjustment nut and remove the cable from the frame bracket.

5. Use a couple clamps to secure the crossmember between the frame rails. Slide it forward to the edge of the body mounts. Drill the holes with a 5/16” bit and thread the 3/8” x 1” self-tapping bolts in one at a time. Do not over tighten the self-tapping bolts; they can be stripped. 6. The location of the upper Shockwave mount is determined by measuring 14 ½” from the edge of the bracket to the large hole in the bottom of the frame. 7.

9. How do you set the pinion angle? On a single-piece 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.

10. Pinion angle must be set at ride height. At ride height there should be 4 1/2” between the axle and frame. 11. One trick to help maintain these setting while welding in the axle bracket is to tack weld a 4 1/2” long spacer between the axle and frame. 12. After setting the pinion angle, make sure the axle is centered. This can done by measuring from the axle flange in to the frame rail. 13. Install the 4 link bars into the crossmember and axle bracket, but do not tighten the bolts yet.

17. Bolt the lower Shockwave mount to the axle bracket using the 5/8” x 3/4” Allen bolt. Apply anti-seize to the threads. It is easier to remove the bars to install these bolts. 18. There is a driver and passenger side bracket, the correct bracket will offset the Shockwave toward the wheel. 19. Bolt the diagonal link into place with a spacer on both sides of it using a 5/8” x 2 3/4” bolt and nyloc. It should measure 30 1/4" C-C. 20. Install the parking brake cable into the new tab on the crossmember. 21.

25. Remove the spacer from between the axle and frame. 26. A new brake line tab is supplied and will mount just below the original. Make sure it clears the bar through full suspension travel. 27. Driving height will be with approximately 13" from center eye to center eye.
