Safety Warning
Certain Zone Offroad 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.

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.
TJ: 32” x 11.50” tire/15x8, 3.5”
B.S. wheel
XJ, ZJ: 30" x 9.50" Tire/15x8,
stock offset wheel
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 components. 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.

INSTALLATION INSTRUCTIONS
1.
Park the vehicle on an appropriate work surface. Ensure that the vehicle is in
park for automatic transmission or in first gear for manual transmissions and the
parking brake is applied. Block the wheels for added safety.
2.
These installation instructions outline the installation for the J2100/J2202 coil
spring spacer kit for the front and rear of a Jeep TJ and ZJ as well as the front of
the Jeep XJ. (2) J2100/J2202 kits will be required to complete the installation
on the front and rear of the TJ and ZJ vehicles.
3.
The following steps outline the installation of the J2100/J2202 kit without the
use of any type of coil compressor device. Using a coil compressor will allow
some of the disassembly steps to be skipped but Zone Offroad does not recommend using a coil compressor during this installation.

ront Installation
1.
(TJ, ZJ and XJ Models)
Remove the bolt mounting the front track bar to the passenger’s side of the axle
Figure 1. Save track bar bolt and nut tab. Allow the track bar to hang free.
Step 1 Note
The track bar bolt may require a
T‑50 Torx socket on early models.
Figure 1
2.
Raise the front of vehicle with a hydraulic jack and place jack stands under the
frame rails, just behind the lower control arm pockets.
3.
Remove the wheels.
4.
All ZJ and 1997 models TJ only: Mark the position of the alignment cam adjusters located at the end of each front lower control arm at the axle Figure 2.
Figure 2
J2200 Installation - pg. 2
5.
6.
Support the front axle with a hydraulic jack. Disconnect the shocks from the
axle. Save the lower shock hardware.
Remove the upper mounting nut from the sway bar links Figure 3. For XJ/ZJ
models remove and save the upper nut and stem hardware. For TJs, disconnect
the links from the sway bar with a pickle fork to release the tapered seat. Save
nut.
Step 5 Note
If replacing the shocks, remove
the shocks from the upper mount
as well and remove from vehicle.
The upper mounting hardware will
not be reused.
Figure 3
7.
Remove the cotter pin and castellated nut from the drag link end at the pitman
arm Figure 4. Thread the nut back on a couple of turns. Strike the pitman arm
near the drag link end to release the tapered seat. Take care not to damage the
end. Remove the nut and the drag link from the pitman arm. Save hardware.
Figure 4
8.
Remove the driver’s side coil spring retainer clip located on the back side of the
axle coil seat. Save clip and bolt.
9.
Loosen the driver’s and passenger’s side lower control arm bolts at the axle.
Completely remove the passenger’s side bolt and leave the driver’s side in
place. This should allow the axle to lower enough to remove and install the coil
springs.
10.
Lower the axle with the hydraulic jack and remove the coil springs. Take care
not to over extend the brake lines.
Step 8 Note
Some models may have a passenger's side retaining clip as well. If
that is the case remove it also.
J2200 Installation - pg. 3
11.
Step 11 Note
Remove the factory rubber bump stop from the upper coil mount Figure 5. Large
pliers can be used to pull it out. Remove the factory bump stop retainer cup by
removing the bolt from the center. Save bumpstop, cup and hardware.
Bump stop removal is not necessary on models equipped with small
diameter bump stops (newer XJs).
On these models the coil spacer ID
is large enough to slide over the
bump stop.
Figure 5
Step 12 Note
The small “lip” on the coil spacer
should point down when it is
installed.
Step 13 Note
A small amount of grease on the
bump stop will make installation
easier.
J2200 Installation - pg. 4
12.
Slide the new coil spring spacer onto the upper coil mount. Leave the factory
coil spacer in place, the new mount will be positioned below it. While holding
the new spacer in place, reinstall the factory retainer cup with the factory bolt.
Torque hardware to 25 ft-lbs.
13.
With the factory retainer cup in place, reinstall the factory rubber bump stop.
14.
Reinstall the factory coil springs and rotate the ends so that they seat properly in
the axle mounts.
15.

Post-Installation
Warnings
1. Check all fasteners for
proper torque. Check to ensure
for adequate clearance between
all rotating, mobile, fixed, and
heated members. Verify clearance
between exhaust and brake lines,
fuel lines, fuel tank, floor boards
and wiring harness. Check steering
gear for clearance. Test and inspect
brake system.
2. Perform steering sweep to
ensure front brake hoses have
adequate slack and do not contact
any rotating, mobile or heated
members. Inspect rear brake hoses
at full extension for adequate
slack. Failure to perform hose
check/ replacement may result in
component failure.
3. Perform head light check and
adjustment.
4. Re-torque all fasteners after
500 miles. Always inspect fasteners and components during routine
servicing.
