6. Remove the plastic top bumper cover.
You may be able to remove the two plastic
screws with a Phillips screwdriver. But it is
likely they’re “frozen” in place and will have to
be pried up with the push-in retainer removal
tool.

7. The factory “crash bar” is the semi-
rectangular tube which runs from one side
to the other, at the front of the Jeep’s frame,
just behind the bumper (the bumper should
already be removed at this point). The
lower corner of the crash bar at either end
must be trimmed for proper fitment of the
RockBrawler bumper. Use an abrasive cut-
off wheel or other suitable cutting tool to trim
off the end of the crash bar. Your cut should
be adjacent to the outside edge of the front
vertical support, or 7/8” inboard from the
outside edge of the outermost frame bracket
as shown in Figure 8.

Do this for both ends of the crash bar. Use
a file or die grinder to de-burr the cut edge,
then apply touch-up paint or clear coat to the
exposed bare metal for protection against
corrosion.
8. Pre-install the RockBrawler bumper onto
the frame. There are eight (8) threaded
studs located on the inside/backside of
the bumper, which will correspond with the
bumper mounting holes on the frame. It
may be a tight fit due to slight manufacturing
variances from Jeep to Jeep, but the bumper
will fit with some gentle persuasion. You may
need to use a rubber mallet or soft dead-blow
hammer to tap the bumper into place. Be
careful not to mar your paint or powdercoat
finish.

Locate the 1/2-13 nylon insert lock nuts and
1/2” flat washers that came in the hardware
kit with your RockBrawler bumper. Install a
flat washer and lock nut onto the two bumper
mounting studs at the outside of the frame rail
on either side of the Jeep. Snug these with
the 3/4” deep socket, extension and ratchet
but do not over-tighten, as the bumper will
