BEFORE YOU BEGIN
The Poison Spyder Customs RockBrawler™ II

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™ II rear bumper on to the

Jeep. The bolt flange of the RockBrawler™

II 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.
