BEFORE YOU BEGIN
The Poison Spyder Customs RockBrawler Rear

Bumper and Tire Carrier come 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.
If powder coating, make sure the entire bumper

and tire carrier are completely disassembled

first. Make sure the latch mechanism, bearings

and races or grease seal are not yet installed.

Make sure your powder-coater understands

that the hinge spindle must be masked off (not

coated).
Do not paint or powder coat the crescent-shaped

stainless steel Lock Pin Slider Plate.
Note that the Spyder Web Gusset Detail is

detachable so that it may be painted or powder

coated a contrasting color from the rest of the

bumper.

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.
