COMP4X4 makes an unbelievable Heavy Duty Rear Bumper that
is ready for rough terrain and trails. Jared; Owner
and Fabricator of COMP4X4 does indeed build according to
their motto;
- "Tuff
Toys. Tuff Competition". These bumpers are also
ready for an added tire swing, which Jared is fabricating
up for us as this is being written. We hope to be on
schedule with this and have one by the first week of
January.

Installation
NOTICE: When removing stock bumper, be sure legs are not
under it while removing to avoid leg injury. Same
warning when installing new steel bumper as it has increased
weight.

1.
Remove plastic ends from my stock bumper.
This makes removing the two bolts on each end much easier
than trying to get an open end wrench into the tight area.

2.
If you have a towing package installed, you will need to
remove this first as it will be in the way when installing
the new bumper.

3.
Remove the bolts that hold the bumper on to the frame of
the Jeep.
4.
COMP4X4 instructions suggest lowering the gas tank in
order to get access to the additional bolts that will be
installed. Rather than lowering the entire gas tank, I
lowered the rear edge of the factory gas tank skid
plate (held by four nuts). This will give you
enough room to fit your hands into the tight area.

5.
Once you have the rear bumper off, this is a good time to
clean the frame and gas tank skid. I had plenty of dry
mud just waiting for me when the stock bumper came off.
6.
Once the stock bumper is off, it is time to measure for the
the new holes to be drilled, center punch and drill
the two sets of holes in the cross member. The new
holes are 8 inches inward from the existing holes from the tock
bumper. Once you drill the holes, you will want to hit
the area with some spray paint to prevent rust.

7. Now, it's time for the bumper installation.
I used a floor jack with a couple of pieces of 2x4
underneath, and raised it up into position. Be sure to
put the bolts in loosely and position the bumper where
desired. One in place, tighten down. You may
want to use a thread lock to give that added strength to
keep in place, although the lock washers will do the job.
8.
After the bumper was installed, I sprayed the
mounting bolts to help keep them from rusting, and to blend
in with the new all black satin bumper.
9. When that was completed I went ahead and
sprayed the stock gas tank skid and tow package to have a
clean and uniform match.

10.
I added D-Shackles for the added recovery points when I am
out mudding. I painted them white for a nice off-set
color. But soon I will have a set of Stainless Steel
Shackles sponsored to JS.
11.
This rear bumper is ready for a Tire swing, which Comp4X4 is
fabricating right now.
