Rear Crossmember Kit

This is the GenRight RBB-1001, a 3/16" thick steel cross member reinforcement kit for the rear cross member on the frame of a Jeep.

It is designed to beef-up your existing rear frame member AND body mounts. It can also  be used as a hi clearance bumper by itself (as we do on our RTC-3200 & 3400 tire carriers) or a reinforcement under a rear bumper.

As you can see in the pictures, you remove the rear most body mounts and install the plate then slip them back in place.

FEATURES:

• C channel design fits over and under frame.
• Laser cut and CNC formed into shape for a perfect fit.
• Allows you to repair or replace damaged rear frame cross members & body mounts (needed on LJ's).
• Allows you to beef up rear frame section.
• Can be installed under an existing rear bumper.
• Can be used by itself as a bumper for a better departure angle.
• Bolt-on design.
• Includes Grade 8 mounting hardware.
• Shipped to you un-painted.

This kit includes:

• (1) Full width laser cut and bent rear plate (RBB-1000)
• (2) Outboard rear frame brackets (can not be used on leaf spring vehicles)
• (1) Grade 8, 7/16-20 Hardware kit

IMPORTANT NOTES:

• Requires dropping the gas tank and the drilling of 2 additional holes in the rear cross member to properly mount it on your Jeep. 
• Optional internal "backing plate" is recommended and available (RBB-1007).
• For proper mounting, it requires removing the fuel tank to drill and access center bolts.
• Is NOT a direct bolt-on for CJ's.
• If this product is being used under a aftermarket rear bumper to beef up or reinforce the rear cross member, you may have to cut off and re-weld the lower tabs on the rear bumper (if your bumper has these tabs to pick up bottom frame holes).
• Holes in plate fit the LED-1500 back up lights.
