TCI Four-Link Kit Install - Double Duty Times Two

The next step is to install the coilover shock crossmember.

But first, the stock crossmember must be removed from the chassis using the same technique used to remove the spring perches.

With the stock crossmember removed, the coilover crossmember can be slid into place. In our case, the stock holes left from the original crossmember will be used to locate the coilover crossmember, but that may not always be so.

Next, the coilover shocks can be installed using the provided bracket adapters for the lower mounts.

Once installed, Jason double checks for level on the shocks themselves using an angle finder. Depending on how far out this reading may be could necessitate adjusting the coilover crossmember.

Everything checks out fine, so the crossmember is bolted in place using the provided 5∕8- inch hardware.

One option Jason decided to add to the rear four-link kit is TCI’s rear anti-roll bar. A hole needs to be bored through the framerail 12 inches ahead of the axle centerline to house the antiroll bar crossmember. To mark this, first Jason makes his mark on the upper fourlink bar.

Then, using a level, he transfers this mark to the framerail. This method is used since the rear axle bumpstop is in the way.

The hole needs to be 1 inch below the top of the framerail as well.

With the location of the hole marked, and centerpunched, Jason uses a 1 1/4-inch hole saw to make the hole.

Here, the crossmember is slid into place.

Next, the crossmember is centered…

…before being welded in place.

Bushings are then inserted into each end of the crossmember to support the antiroll bar…

…followed by the splined bar itself. Brass washers are then used between the bushings and the torsion arms.

Each torsion bar is then mated via rod end links to the top four-link attachment point using a special stud.

A pinch bolt at the splined end keeps the arms in place. It should be noted that both arms must be timed or mounted in the same position on either end.
