BEFORE YOU BEGIN
The Poison Spyder Customs RockBrawler Rear
Bumper comes as unpainted, bare steel. You will
want to either powder coat or paint the bumper
prior to final installation. If painting yourself,
careful preparation will make a big difference
in the quality and longevity of your paint job,
even using “rattle can” aerosol paints. Begin
by thoroughly cleaning the bumper with solvent
or de-greaser, then make sure all residue is
removed. Even if you use cheap paint, try to
use a good quality primer. “Etching” primers are
best to use on bare, unpainted metal. Allow it to
properly dry before painting, and between paint
coats.
INSTALLATION PROCEDURE
1. Park the Jeep on a flat, level surface and
set the parking brake.
2. Remove existing rear bumper and
disconnect the rear sway bar where it bolts
to the outside of the frame rails. Keep the
OE hardware that attached the bumper to
the frame rails, as some of it will be re-used.
3. With the help of a friend, pre-install the
RockBrawler™ rear bumper on to the Jeep.
The bolt flange of the RockBrawler™ bumper
will mount between the outside of the frame
rail and the sway bar bracket. Note that
there are three bolt holes in the bolt flange
on each side of the bumper. Two of these
bolt holes will align with the stock bolt holes
in the frame rail, where the sway bar bracket
attaches. Use the OE hardware to secure
the bumper in place using these two bolt
locations on either side. On the driver side
with the Floating Mount Plate, tighten the
hardware attaching the plate to the bumper,
after ensuring that the bumper is properly
centered and aligned.
4. Use a felt-tip pen or 3/8 center punch to
mark the location of the third bolt hole on the
frame rail, for each side.
5. Look underneath the bumper, note that
there are 4 bolt holes along the bottom
surface of the bumper. The driver’s side,
outside hole will need to be marked to drill a
corresponding hole in the crossmember that
sits just behind it. Use a center-punch or
fine-tip felt marker to mark the hole location.
You may notice that the outside passenger
side already has a through-hole through the
crossmember. Disregard the two center
holes.
