INSTALLATION PROCEDURE
1. Park the Jeep on a flat, level surface and
set the parking brake.
2. Remove existing rear bumper. If it is
the stock bumper, use a T27 Torx driver to
remove the plastic bumper extensions, then
use an 18mm socket and ratchet remove
the large nuts/bolts from the frame rail side
brackets and along the bottom of the bumper.
Keep the OE hardware as some of it will be
re-used.
3. Remove the pre-installed 3/8-16 nylon
insert lock nuts and washers from the Bolt
Plates on the inside of the RockBrawler
bumper. Do not remove the Keeper Washers
that hold the Bolt Plates in place. Note that
there are several sets of unused bolt slots
on the bumper’s internal mounting surface.
These are for different Jeep models, please
disregard them for your application.
4. Install the RockBrawler bumper. The bolts
in the captured bolt plates will align with the
mounting holes in the Jeep’s frame/bumper
brackets. The Bolt plates are captured in
horizontal slots to allow for some adjustment
and manufacturing variances in the Jeep’s
frame. Install the provided 3/8-16 nylon
insert lock nuts and 3/8 flat washers on to
the threaded studs of the Bolt Plates, where
they protrude through the Jeep’s mounting
bracket. Do not fully tighten them at this time.
5. Use two (2) of the 10mm OE mounting bolts
(18mm wrench size) to bolt through the slots
located along the underside of the bumper
into the OE welded-in-place nuts inside the
rear crossmember. Do not fully tighten them
at this time.
6. With all hardware installed, check that the
bumper is level and correctly aligned with the
Jeep, as the slots in the Bolt Plates will allow
for a small amount of adjustment. It may be
easiest to slightly tighten each of the bolts
then use a soft dead blow hammer or rubber
mallet to lightly tap the bumper to make fine
adjustments.
7. Once the bumper is correctly levelled and
aligned, tighten all mounting bolts to 45 ft./
lbs.
NOTE: The photos shown in the following steps
depict the tire carrier installation on a JK version
of the RockBrawler Rear Bumper, however the
procedure is the same for the TJ/YJ/CJ version.
8. Use the two (2) supplied 3/16” pop rivets
to attach the crescent-shaped stainless steel
Lock Pin Slider Plate to the bumper at the
base of the hinge spindle.

9. Wearing latex or nitrile gloves, “Pack” the
two tapered roller bearings with a quality
wheel bearing grease by hand or with a
bearing packing tool. The two matching
bearing races are already pressed in to the
tire carrier hinge housing.
10. Wearing a latex or nitrile glove, use your
fingers to apply a light sheen of grease to the
bare metal surfaces of the inside of the tire
carrier hinge housing and bearing races, as
well as the hinge spindle on the bumper (do
not coat the threads for the spindle nut). This
will help discourage rust formation on these
bare metal surfaces.
11. Insert a Tapered Roller Bearing into the
pre-installed Lower Race, inside the Hinge
Housing. Ensure that it seats correctly and
