1. Start by lifting the vehicle safely on a flat
surface. Remove all wheels including the
Spare Tire. Support vehicle by the frame
rails.
Hint; Take pre and post measurements of
the vehicle height. Measure from the center
of the wheel or hub to the bottom of fender
opening. Record your findings for all four
corners.
Recording measurements (Step 1)
2. Beginning with the rear suspension, properly
support the axle housing.
Support the rear axle (Step 2)
3. Disconnect the sway bar by removing the
two brackets (four bolts) on the axle
housing.
Remove sway bar bolts (Step 3)
4. Remove the shock top nut. It may be
necessary to hold the shock body stationary
to keep it from rotating. Remove lower bolt
and remove shock.
Remove the shock and coil one side at a
time.

5. Allow the rear axle to safely/ slowly droop
allowing removal of the coil spring. If
necessary, pry or pull down on the housing
to unseat the spring. The springs should be
removed with minimal effort.
Note; Use caution as not to overly extend
and or damage any ABS or Brake lines.
Install the new coil spring. Ensure proper
placement of the upper and lower spring
perches. Rotate if necessary to properly
seat.
Note; Some coil spring applications include
a short and long spring. The longer spring
installs on the driver’s side of the vehicle.
Install the OME Coil (Step 5)
6. Install the shock with included bushings (see
photo for bushing/washer orientation). The
index washers must be properly seated in
the mounting hole (with the “steps” facing
each other).
Repeat steps 4-6 for opposite shock and
spring installation.
Note; It will be necessary to use a jack to
raise the rear axle to align the lower shock
eyelets.
Washer, bushing and nut orientation (Step 6)
7. Install sway bar and bracket(s). It will be
necessary to use a jack to lift sway bar into
the proper location.

25. Verify the entire installation and insure all
bolts and nuts have been properly Torqued
to factory specifications. Record post vehicle
height measurements as performed in step
one.
Hint; Side to side height adjustments are
made by adjusting anchor arm bolts with
suspension extended (wheels off the
ground).
Do not adjust the torsion bars with the
vehicles wheels on the ground.
Torsion Bar Adjustment Bolt (Step 25)
Adjusting Torsion Bars Properly (Droop)
Once the entire installation is complete the droop must be checked for proper vehicle height. The first
measurement should be taken at ride height (all the vehicle weight is on the wheels - photo A).
The second measurement should be taken with the wheels off of the ground (suspension fully extended photo B).
Subtract the first measurement from the second measurement; the difference is the amount of droop or
down travel. We prefer a minimum of 50MM to 60MM of downward travel (droop). This is the maximum
vehicle height; however a lower height may be desired. Perform any adjustment(s) with the Torsion bar
Adjustment Bolt as necessary. Tighten the Torsion Bar Adjustment Bolt to raise the vehicle (less droop).
Loosen the Adjustment Bolt to lower the vehicle (more droop). Excessive vehicle height will not allow for a
proper alignment causing instability such as wandering, torque steer and pulling.
Important; all torsion bar adjustments must be done with the vehicle completely raised off the ground
and the front suspension hanging. Do not adjust the torsion bars with the vehicles wheels on the ground.
While completing the height adjustments on the suspension, it may be necessary to re-clock one or both
of the torsion bars. This is required if the Adjustment Bolt runs out of thread or hangs below the frame.
Final desired lift height is achieved with a minimum 50MM to 60MM of droop.
A
The difference between the
two measurements is equal to
the droop achieved.
B
Hint; you may also refer to OME’s guidelines for Torsion Bar adjustments (posted on
http://www.sleeoffroad.com/installation/torsionbar_adjustment.pdf).
An Alignment and Zero Point calibration (vehicles equipped with VSC) are required immediately after the
suspension has been installed.
