When determining where to mount the upper ShockWave mount, measure 20 1/4 inches from the edge of the crossmember bracket to the large hole at the bottom of the frame.
Once the mounting point is located, mount the upper ShockWave mount. Be sure to use the correct mount because there is a driver- and passenger-side mount.
Mount the four-link bars to the crossmember mount, but do not tighten them down yet.
So far, the setup should look something like this. The crossmember is secured and the four-link bars are installed on the crossmember.
Before installing the ShockWave 7000s, apply thread sealant on the air fittings and then screw the air fitting into the ShockWave.
Hang the ShockWaves from the upper mount.
Although you can do the work with the rearend under the car, ours was already out and we decided to handle the build out in the open. When installing the axle brackets, there are several things to accomplish. First, make sure the driver- and passenger-side brackets (the passenger-side bracket has the diagonal link bracket welded to it) are installed on the correlating axle sides. Second, the brackets should be welded into place 31 11/16 inches apart on the outside measurement, then center the bracket between the axle flanges; the brackets should be mounted 90 degrees with the pinion.
