INSTALLATION INSTRUCTIONS
1. Place the vehicle in neutral. Raise the front of the vehicle with a jack to slightly raise the tires of the ground and
support the frame with jack stands beneath each frame
rail behind the lower control arms. Installation is done one
side at a time, starting with the driver side. The torsion bar
adjusters are under the cab of the vehicle at the rearward
end of the torsion bars.
2. Measure or make a note of how much thread is remaining
on the torsion bar adjuster bolt. You will reset the bars at
this same location with the new adjusters.
Use extreme caution when loading and unloading the
torsion bars; there is a tremendous amount of energy
stored in them. Keep your hands and body clear of the
adjuster arm assembly and the puller tool in case anything
slips or breaks. Note: Because of the extreme loads
generated by the torsion bars on these vehicles, a
standard tow-jaw puller may bend the “lips” of the cross
member and my pop out of place. For best results use a
torsion bar puller tool. If you cannot find one locally, this
tool (J-22517-C) is available from Kent Moore Tools in
Roseville, Michigan (800-345-2233) or a Ball Joint
Remover like OTC7249 can be used.
3. On the driver side, using a torsion bar removal tool,
remove the stock torsion bar adjuster. Loading the torsion
bar using the tool, removing the bolt and nut block, does
this. Unload the bar; slide the torsion bar forward allowing
the OE torsion key to fall out.
4. Install the new torsion bar adjuster using the torsion bar
tool. Reinstall the threaded block and adjuster bolt.
5. Repeat steps for passenger side. Making sure the driver and passenger side torsion bar adjuster bolts are
adjusted the same amount. Fine-tuning is done in a later step.
6. After the torsion bar adjusters have been installed and tightened to the factory measurement taken in step #2.
7. Jack up the front of the vehicle and remove the jack stands. Lower the vehicle to the ground to where the torsion
bars are supporting the weight of the vehicle. Check for level.
8. Additional adjustment may need to be performed to level the vehicle by either tightening or loosening the torsion
bars. This is done with a floor jack supporting the side of the vehicle that is being adjusted, raising the tires slightly
of the ground and only adjusting the bolt 1-2 turns at a time to ensure the leveling of the truck. After adjustment
lower the vehicle to the ground and recheck for level. This may take several attempts.
9. Remove the stock shock absorbers at this time and install the new Rough Country shocks if purchased with kit.
This kit will level the vehicle without a substantial difference in ride quality. Most customers adjust the front to 2" higher than
stock, and are satisfied with the ride quality. Ride quality is inversely proportional to heights ABOVE a 2" adjustment. This
leveling kit works within the range of the FACTORY droop, or downward suspension cycle. It does NOT bind the CV axles or ball
joints, just as none of these conditions occur with the truck supported on a hoist and the front wheels hanging freely in the air. As
with any lift installed, adjustment of the front headlights is required after installation. Note – the air dam on the front may need to
be trimmed for additional clearance, depending on the tire size.
A front-end alignment should ALWAYS be checked after installing ANY vehicle suspension lift. This kit typically requires a
slight toe-in adjustment. Record the ride height measurement at the time of alignment. If, in the future the torsion bars
settle excessively, alignment can be restored by adjusting-up the bars to their original ride height.
