Grand Cherokee WJ Rear Bumper

WJ Rear Bumper 

The Construction

• If your evap canister is located behind the driver side rear wheel well, you'll have to relocate it. There are multiple writeups on Jeep Forum where and how to relocate it. 
• Arrives BARE STEEL. Painting or powder coating is required
• !!!The swing out DOES NOT rattle! If you know me and how I design and build, if this thing rattled it would have been discarded. For the swing out prototype I used a 1,000lbs spindle, a spring loaded pin and a standard latch to lock it. That's what I had in stock when I built it so I rolled with it. Although it passed testing, I'm not a fan of the standard spindle you see in the photos. The final production model will have a double sheer hinge with bearings. The locking latch also has a pin slot for maximum guarantee it can't unlatch and swing open while driving. I've seen other tire swing outs open while offroading and couldn't believe the designers did not take that into consideration!
• The bottom of the bumper is one piece 3/16 thick plate from fender to fender. The tow hitch is constructed of 3/16 square tube (2"x2"x.188 wall). The center receiver is 1/4" thick from Curt manufacturing and welded through the 2" cross member. The shackle tabs are welded in through the cross member and the frame rail mounting plates. The frame-rail mounting plates are 3/16 thick, are cnc bent and have gussets welded for additional reinforcement. The tow hitch construction is welded to the bottom pate of the bumper. The upper center section and side wings are constructed from 10-gauge plates. 
• High clearance - sits as tight as possible to body lines without major trimming of unibody
• Replaces factory tow hitch with heavy duty hitch construction and welded through 3/4" thick recovery shackle tabs. The tow hitch construction and shackle tab recovery points are welded through one another. See photos for example
• Select between standard shackle tabs or rhino tabs with upper hooks
• 7-pin Tow Hitch Wiring harness Adapter plug included 
• Built in skid resistant corner steps with reverse dimpled steel 
• can be built with-out the corner steps if you don't need them. We'll simply cover them with additional plating like it was never there, but they'll still be there, you just won't see them
• Reverse dimpled plate near quarter panel provides additional step to access roof (for us short folk, you tall folk don't have the need for this but it's there)
• Can be built without the reverse dimpled plate near the quarter panel, we'll just replace the dimpled plate with a solid flat plate. You have choices
• Mounts to six factory tow hitch mounting points under frame-rail plus four upper unibody pinch seam mounting points (drilling required - 4 holes). Ten mounting points total. The upper four mounting points are next to the tail-light which is the unibody pinch seam. With six bolts under the frame rail and 4 bolts on the upper portion of the bumper, it has a solid mounting pattern. No need to drop fuel tank or tank skid plate
• Some minor trimming and folding of rear unibody cross member is required and simple to do. See photos of Bash hammering in that section using a 4-lbs sledge
• Not compatible with the evap canister located behind the wheel well. Either relocate the evap canister or request us to cut the bumper to clear your evap canister prior to shipment - no charge, we'll chop it for you
• Testing phases prior to release:
• Banging, slamming, scraping, some more slamming bumper on boulders through rough terrain at Couger Buttes in Southern California. Testing for movement of bumper from mounting points, tweaks in the plates or construction, denting, bending etc. = Testing Phase Complete - Passed
• 575lbs tongue weight Shock force testing on the receiver hitch - Passed
• Swing out is tested to 235-lbs from Los Angeles California to Table Mesa Arizona, through the trails of Upper & Lower Terminator, Judgement Day and back to Los Angeles. The swing out hinge, latch and lock pin is solid.
• Class III Tow Hitch Certification - Out for certification. Estimated time for completion is end of May. As of April 2nd, 2024, the hitch is not yet certified as a class III tow hitch until it completes its certification testing process. The tow hitch on this bumper is designed and built stronger than the factory hitch but I can not advise you to tow on public roads. Until the certification process is complete, the tow hitch construction is labeled as "Offroad Recovery Use ONLY". Tow at your own risk and discretion.
