I know its a unibody.. I should of re phrased to read reinforce between frame rails at the rear of the xj of the unit body I just thought that some of you smarter guys would overlook look the way I phrased it and woiuld help
sort of like a strong bumper But attaching the two frame rails of the Unibody at the rear of the vehicle. Just wanted some Ideas that’s all …..maybe some pics

There is no better solution than a good rear bumper with good mounting points (hitch holes + all 8 bumper holes).
I'm sure you can find pictures of rear bumpers.

i took a piece of 4" x 3/16" flat stock, drilled holes for the bumper mounts, made openings for the frame rail openings and soon for the gas tank straps, and welded a piece of 1" x 3/16" flat 90 degrees at the bottom for rigidity. right now it is bolted with the bumper bolts....but once my rear bumper is finished, I will drill a few more holes and add some rosette welds.

if that makes sense. here's a pic

that's good for building a rear bumper.....but it's a good idea to reinforce the rear crossmember (especially if you chop the top), as cracking starts to occur there. i beleive goatman had some issues with that

I'm taking this on next weekend. A piece of 4x2x.120 is perfect, cut the old junk out and weld the rectangle in. Drill your bumper mount holes first.

Only reason is that I'm bending a new "prerunner" style bumper, and they just don't have the structural integrity of a rectangle bumper.

Don't forget to reinforce the fuel filler hose area as well.

As others have said a strong bumper/hitch tied into the rails will help a lot with rigidity but if you want to go even further you could add extra crossbraces.

Here are a couple I made when going to rear coils... went overboard as I plan on cutting the top and will need the extra bracing.

thats a aesome coil over job...is that exaust coming out of the rear quarter panel!? very cool

 

[flexy92xj]

exhaust does exit out the quarter panel (for now) as I was sick of smashing the tailpipe on rocks. Going to trim the quarters some more and then will run the exhaust through the bumper.

heres a better shot of it...

Man that seems like a lot of work and money to just run 33's... all the more power to you, I think you did an awesome job. Custom Suspension work aint easy or cheap, why go thru all the hassle just to run 33's?

Looks good!

It will be on 35s shortly. It was a lot of work but well worth it in the ride/travel/rigidity areas... plus with plans for a high hp stroker I want to put the power down without axle wrap.
