5.5" Lift System
Read and understand all instructions and warnings prior to installation of product and
operation of vehicle.
Zone Offroad Products recommends this system be installed by a professional technician. In addition to these instructions, professional knowledge of disassembly/ reassembly procedures and post installation checks must be known. Minimum tool requirements
include the following: Assorted metric and standard wrenches, hammer, hydraulic floor jack and a set of jack stands. See the "Special
Tools Required" section for additional tools needed to complete this installation properly and safely.
»»Product Safety Warning
Certain Zone Suspension Products are intended to improve off-road performance. Modifying 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 modified 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 modified vehicle under the influence of alcohol or drugs. Always drive your modified 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.
305/55/20 w/ 5-1/4" Backspacing
295/70/17 or 18 w/ 4-1/2" Backspacing
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. Post suspension system vehicles may experience drive line vibrations. Angles may require tuning, slider on shaft may require
replacement, shafts may need to be lengthened or trued, and U-joints may need to be replaced.
5. Secure and properly block vehicle prior to installation of Zone Offroad Products. Always wear safety glasses when using power
tools.
6. If installation is to be performed without a hoist, Zone Offroad Products recommends rear alterations first.
7. Due to payload options and initial ride height variances, the amount of lift is a base figure. Final ride height dimensions may vary
in accordance to original vehicle attitude. Always measure the attitude prior to beginning installation.

Rivet Nut Installation Instructions
»»Hole Preparation
83.
Drill hole to appropriate size for rivet nut installation. 1/2" Rivnuts require an
11/16" hole and 3/8" Rivnuts require a 17/32" drill. It is crititcal that this hole is
drilled to the correct size. Remove any burrs that could keep the rivet nut from
seating flat against either side of the hole surface. Figure 1A/B.
Step 83 Note
If the correct drill size is not available, it is possible to drill the hole
to an available smaller size and
slowly grind it out to until the rivetnut fits tight.

Place the installation tool with the rivet nut threaded on the end into the appropriately sized hole.
88.
For a 3/8" rivet nut, hold the nut closest to the rivet nut still with an 5/8" wrench
and tighten the 3/8" bolt with a 9/16 wrench to set the rivet nut. Be sure to hold
the rivet nut flush to the surface and square to the hole as it is tightened. Figure 4
89.
For a 1/2" rivet nut, hold the nut closest to the rivet nut still with an 7/8" wrench
and tighten the 1/2" bolt with a 3/4" wrench to set the rivet nut. Be sure to hold
the rivet nut flush to the surface and square to the hole as it is tightened. Figure 4
Step 88 & 89 Note
If available, an impact gun is
recommended for tightening the
bolt to ensure the rivet nut remains
sqaure to the hole and to ease holding the nut from spinning.

Figure 4 - 1/2" Rivet Nut shown
Step 90 & 91 Note
If using the recommended inpact
gun, use caution to not exceed the
recommended torque specificatons.
Step 92 *IMPORTANT*
It is very important to hold the nut
as the bolt is loosened because the
grip of the star washer will try
to spin the rivet nut and ruin the
installation.
