Installation Instructions
Please note that modifying the suspension of your Jeep Wrangler
will affect the vehicle handling and stability characteristics!
* For clearance it may be necessary to use a 1" body lift and/or
different type of fender flares. Some bodytrimming may also be
necessary depending upon application.
You have purchased a RockJock® suspension lift system for
1997-2006 Jeep Wrangler. This suspension system
will provide ample lift to accommodate up to 35" tall tires.* A
4½” back spacing wheel was used for thedevelopment of this kit.
Other wheel & tire configurations can be used but interference
may be an issue.

Check length of all of the new Johnny Joint® control arms prior
to installing. Compare the length of yourexisting control arms to
the Currie Arms.
When measuring, measure from the center of the thru bolt hole to
the center of the thru-bolt hole on theother end. This measurement
can also be determined by measuring the overall length of the
control arm andsubtracting 2" for upper arms and 2 ½” for lower
arms.
Currie control arms come preset for a TJ with a 4" lift, a
transfer casetailshaft shortening kit, and a CV driveshaft.
Front upper arms - 15" c-c
Rear upper arms - 13 1/2" c-cAll lower arms - 15 3/4" c-c
When custom adjusting the arms for your application, you
should
never have any more than 3/4" of thread showing from beyond
thejam nut. If more than 3/4” is showing after you’ve adjusted the
arms,you should contact Currie Enterprises technical department to
discuss
your application and installation.
The upper control arms are supplied with 7/16" bolts. The upper
control arm frame and housing brackets onJeep TJ’s have metric
holes. You will need to drill out these metric holes to accommodate
the 7/16” bolts.
Torque the 7/16" bolts to 60 ft lbs. of torque.
Torque all of the 9/16" bolts on the lower control arms to 90 ft
lbs. of torque.
Grease all fittings with multi-purpose grease and grease
regularly.
Check all jam nuts on control arms after 100 miles and regularly
thereafter. Re-attach emergency brake cablesto control arms with
zip ties, discarding the original brackets. Make sure there is
enough slack in the cable toallow for wheel travel.
NOTE 1: Johnny Joint rod ends are fully rebuildable! Contact
Currie Enterprises for details, or order online
atwww.currieenterprises.com
NOTE 2: The larger washers supplied with the lower control arms
are for use with the the front lower arms
where they bolt onto the axle housing. Discard the other set of
large washers.

1. Remove the original trac bar by unbolting it at the housing
and then at the frame. Retain the torx bolt andfactory nut plate
from the housing for reuse (retained with CE-9120TJS only - new
housing bolt is provided with
CE-9120TJJ). An optional, stronger hex head bolt is available
through Jeep to replace this bolt and is highlyrecommended. Jeep
part #06504416.
2. Using a 5/8” drill bit, drill out the hole in the trac bar
frame bracket on the driver’s side of the frame.
3. Install the 5/8” bolt into the new trac bar through the
bottom side of the Johnny Joint®. The bottom of theJohnny Joint® is
the side without the large flange sticking out of it.
4. Use the special, .200” thick, washer on top of the factory
trac bar bracket
5. Install the new trac bar into the hole that you just drilled
out from the bottom side of the trac bar frame
bracket. Install the nut on the top and snug it down at this
time.
6. Center the front axle assembly under the Jeep by measuring
from the side of the frame rail to a tread line inthe center of
your tire. Make sure you measure to the same place on both sides!
You can center the axle by usinga ratchet strap if necessary.
7. Adjust the track bar to fit the centered axle assembly. When
using the CE-9120TJS trac bar, install the original
housing bolt through the housing end of the trac bar and thread
it back into the original nut plate, but do nottighten.If you are
using the CE-9120TJJ trac bar, it will be necessary to drill out
the hole in the housing bracket to 1/2” to
accept the new, heavier bolt that is supplied. A new nut plate
is supplied for the heavier bolt. Remove the stocknut plate and
insert the new one in it’s place. In some cases it may be necessary
to open up the “access hole”on the bottom of the trac bar bracket
to remove the factory nut plate. Thread the new bolt into the new
nut plate,
but do not tighten.
8. Remeasure your front axle assembly to make sure it’s
centered. Readjust it if necessary.
9. Now go back and tighten and torque all of the bolts.5/8” bolt
at the frame = 125 ft. lbs.Stock torx bolt on the housing = 50 ft.
lbs.
Optional 1/2” bolt on the housing = 75 ft. lbs.Jam nut = really
really tight!
10. Confirm that the Johnny Joint® is straight and in a
relatively neutral position, and that the mount on thehousing is
straight and not in any kind of bind. If anything is misaligned
readjust it and retighten it before use!

Bar Relocation Bracket
CE-9123 - Johnny Joint Adjustable Rear Trac Bar WITH Trac Bar
Relocation Bracket (for use with Currie
rearends or rearends that already have a relocation bracket
installed)
1. Remove the original trac bar by unbolting it at the
housing.
2. Install the new Currie bolt-on trac bar relocator bracket by
attaching it to the existing bracket with the large
supplied bolt. Then go back and mark all of the smaller holes
using the bracket as a template. Drill all holes andinstall
bolts.Note 1: If you have a Currie rearend this bracket is not
needed - the bracket on the Currie rearend accounts for all
of this.Note 2: You may also modify the stock bracket that is
already on your rearend. This would require welding andwe do not
supply instructions for doing this.
3. Before installing the trac bar, put anti-seize lube on the 1”
threads.
4. Install the solid bushing end of the trac bar into the frame
bracket using the stock bolt. Snug the bolt, but do
not tighten.
5. Center the rear axle assembly under the Jeep by measuring
from the side of the frame rail to a tread line inthe center of
your tire. Make sure you measure to the same place on both sides!
You can center the axle by usinga ratchet strap if necessary, or by
pushing on the side of the Jeep.
6. Adjust the track bar to fit the centered axle assembly.
Install the Johnny Joint® end into the housing bracket
and install the greasable bolt through the hole. Snug the bolt,
but do night tighten.
8. Remeasure your rear axle assembly to make sure it’s centered.
Readjust it if necessary.
9. Now go back and tighten and torque all of the bolts.Mounting
bolts at the frame and housing = 50 ft. lbs.Jam nut = really really
tight!
10. Confirm that the Johnny Joint® is straight and in a
relatively neutral position, and that the bushing at the
frame is straight and not in any kind of bind. If anything is
misaligned readjust it and retighten it before use!
NOTE: Check torque specs regularly!
