really liked my Petroworks nerf
bars but after the last run to Pyeatt Draw I noticed the front frame
outrigger where the nerf bar mounts was collapsing. As a
result when I put the door back on after the run I couldn't close
it. I feel if you weld a 1/4" steel plate to both front
and rear mounting points you'll probably avoid this problem.
Since I am expecting to try even harder trails I decided to just
beef up the rocker panel protection as much as possible. Based
on some research the best way to do this on a Samurai seems to be to
attach some steel angle to the frame so it sits directly under the
rocker panel. This way all of the force from impacts will be
spread amongst the frame mounts and the entire length of the rocker
panel. With a tube style nerf bar, once the mount fails all
the force is centered on the two points where the bars pass under
the rocker panel.
20 ft 4.00 x 4.00 x
.25" Steel Angle - $47
Cut off Wheels
Mounting Bolts ( I
used 3/8" hardware)
I based my
rocker panel sliders off of an article I found on Off-Road.com.
I made a few changes for my setup. First I
cut the angle longer than the instructions said to. I cut them
to 47" and then contoured the ends to follow the body lines.
Another difference was
on the rear mount. I welded a piece of angle to the frame and
mounted the new nerf bar to this instead of the thin piece of stock
frame right above the rear spring mount.
I reinforced the frame
for the front mount by welding a 1/4" steel plate to the inside
of the frame outrigger.
The finished product.
Only thing left to do is fill in the small gap between the rocker
panel and angle with some paintable silicon.
