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.
