Rancho's 4-inch lift kit includes a skid plate, bump stops, brake hoses, a reinforced MIG-welded subframe, rear riser blocks and U-bolts, and drop brackets for the front differential and torsion bars.
|
With the vehicle on a lift or jackstands, the first step is to remove the stock suspension pieces such as the torsion bars and its crossmember.
|
Next unbolt and remove the steering knuckle, shock absorber and lower control arm on each side.
|
The reinforced subframe for the transfer case is pretty heavy, so get some help to lift it in place.
|
Here you can see the amount of drop in the transfer case provided by the subframe to produce four inches of lift.
|
All of these drop-down brackets need to be fitted loosely before tightening the bolts.
|
The new, longer end link for the front swaybar has urethane (red) bushings for less suspension deflection.
|
A side-by-side comparison of the stock (left) and Rancho (right) steering knuckles clearly shows the 4-inch lift. After relocating the stock hubs on the new steering knuckles, install them back on the chassis.
|
Cut off 1/2-inch from the tie rod so the steering can be correctly aligned.
|
The kit includes OEM-quality extensions for the brake lines.
|
The longer Rancho shock absorbers are bolted on the chassis.
|
Rancho's bump-stop has a spacer to compensate for the lift in the suspension.
|
The aft braces included with the lift kit have urethane bushings to minimize suspension deflection and binding.
|
A bit of bending on the exhaust system may be needed to provide enough driveshaft clearance, or you can splice in a curved tube.
|
To install the drop-down brackets for the torsion bars, you'll need to tap a bolthole in the frame members. Once the drop-down brackets are installed, you can replace the torsion bar crossmember.
|
You'll need a C-clamp to put tension on the "pork chop" for the torsion bar.
|
To lift the rear end, start by removing the stock shocks, and then install the lift brackets for the rear bump stops.
|
Install the new, longer Rancho shocks.
|
Unbolt the brackets for the leaf springs to install the riser blocks. The riser blocks fit between the leaf springs and the axle.
|
With the blocks in place, you can then secure them with the taller U-bolts supplied with the lift kit.
