»Product Safety Warning
Certain Zone Suspension Products are intended to improve off-road performance. Modi-
fying your vehicle for off-road use may result in the vehicle handling differently than a
factory equipped vehicle. Extreme care must be used to prevent loss of control or vehicle
rollover. Failure to drive your modied vehicle safely may result in serious injury or death.
Zone Offroad Products does not recommend the combined use of suspension lifts, body
lifts, or other lifting devices.
You should never operate your modied vehicle under the inuence of alcohol or drugs.
Always drive your modied vehicle at reduced speeds to ensure your ability to control your
vehicle under all driving conditions. Always wear your seat belt.
»Pre-inStallation noteS
1. Special literature required: OE Service Manual for model/year of vehicle. Refer to manual for proper disassembly/reassembly
procedures of OE and related components.
2. Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the OE manual.
3. Larger rim and tire combinations may increase leverage on suspension, steering, and related components. When selecting
combinations larger than OE, consider the additional stress you could be inducing on the OE and related components.
4. Secure and properly block vehicle prior to installation of Zone Offroad Products. Always wear safety glasses when using
power tools.
5. Zone Offroad Products body lifts are designed to be used on vehicles in good operating condition. It is not recommended that
body lifts be used on vehicles in poor physical shape. This includes rusted body mounts, damaged or worn frame-to-body
mounting brackets, and poor mechanical condition. Perform a visual inspection of the vehicle before beginning installation.

Remove the wire loom from the retain clips (approximately 4 total) and remove
the clips from the core support. The clips will not be reused. Be sure that the
lower portion of the fan shroud lip is clear from the bottom edge of the core sup-
port so it is able to drop while the body is lifted. If the vehicle is equipped with a
front skid plate, removing the skid plate will aid in accessing the clips.

block) under the passenger’s side so that the weight is evenly distributed on the
jack. Slowly raise body, checking for any wires or hoses that may be binding or
stretching. Lift the body just high enough to install the large 3" diameter body
spacers.
22. Install 12mm x 140mm bolts and 7/16” USS washers in all the body mounts in
combination with the factory body bushing assemblies. The front mount uses the
thick 1-3/4” diameter washers on the bolt that is installed from the top through
the access hole in the body. Fasten the front bolt with a 7/16” USS washers and
12mm nuts along with the factory bushing assemblies. Do not tighten body
mount bolts at this time.

body mount bolts to 65 ft-lbs.
»Bed liFt
25. Loosen but do not remove all bed mounting bolts (six on short bed, eight on
long).
26. Remove the bolts from one side of the bed. Using a hydraulic jack and a block
of wood, lift the bed just high enough to install the body spacers. Install 12mm
x 70mm bolts and 7/16” washers in the body spacers but do not tighten.
27. Repeat the lifting procedure for the other side of the vehicle. Align the bed to the
cab and tighten all mounting hardware. Use Loctite® on all mounting hardware.
28. Remove the rubber pads from the frame where the bed’s cross members origi-
nally rested (four locations on long beds, two on short beds). Place the metal
body spacers at these locations. Figure 15 Attach the spacers to the frame with
5/16" x 3/4” self-tapping bolts. Tighten hardware to 10 ft-lbs.
Step 22 Note
