The
Rubicon 52 is a bumper designed for the vehicle
that is used for intense and technical off road
maneuvering. 60” to 52” modifications
are: outer wing sections have been shortened. This
is achieved with the lower form elevating to a higher
point at the end cap. This end cap has also been
scaled down in size. The top back edge of the wing
was trimmed 1 ½” for tire clearance.
Even though the bumper has been scaled down in size,
it still has a proportionate appearance. It has
been noted that after tightening up on the outer
wings, we created a problem. That being a clearance
issue with Curries Anti Rock Sway-Bar for the TJ.
The lower flange of the bumper contacts the Sway-Bar
Arm. A relief cut and boxing the bumper flange will
need to be done.
Moving
on, the Rubicon 52 has the traditional 45° forms
in the lower face of the bumper that have been a
standard design feature since 1991 and is in a patent
pending procedure. This forming method allows for
more approach and departure angles. This design
also drops the winch down 2” lower into the
bumper to assist in radiator air flow and lower
center of gravity to a tiny degree.
The dropped
winch deck has a recess built into it to accommodate
the cooling fins and longer motor of the Warn HS9500I
and the 9500Ti. The bumper will accept Ramsey, Milemarker
and Superwinch and other Warns of the 9500 lb. class
or smaller that have a 4 ½” x 10”
bolt pattern to match the pre-cut holes in the bumper.
A Fairlead mount will be needed to utilize the hawse
or rollers that come with the winch. For upright
Warn winches, the 8274 WM will be necessary.
One other
thing, trail bumpers of this caliber would be incomplete
without a recovery point. So, we provide Clevis
tabs to be used with the popular ¾”
Clevis. These use a 7/8” screw pin. Our Clevis
tabs are burned from 1” steel and are drilled
for the 7/8” pin. When installed, centered
on the 45° form, they receive about 10 ½”
of ¼” wide continuous weld. With the
combination of thick material, large surface area,
a lot of weld and positioned on the form line, well,
these puppies are on there. They are also placed
approximately 2” off of the front center section
of the bumper on the wing face. This points them
16° side ways to relieve the Clevis of stress
created from a side pull when your only anchor point
is ‘over there’. If a straight pull
is done, 16° is not going to stress a Clevis.
Theoretically, if we kept to these numbers, there
would be a 64° range of motion for the cable.
32° on each side of center line.
Mounting:
These bumpers bolt up in the stock mounting holes.
Auxiliary tabs are supplied for TJ. Adequate fasteners
are supplied with the bumpers.
