XJ Flat Belly/ X member Build. Is it possible? Let's see....

Well, thought I'd do a build on this separate from my XJ build. For those who don't know, my XJ is on about 3" of lift and 35's. I wheel my XJ in big pointy rocks that love to rip on anything they can on the bottom of my rig. I love the low stance of my heep and it works well, but it has it's drawbacks. EVERYTHING under my XJ has been taken into consideration because of it's low height. When you are this low, you rub and drag on rocks a lot. Is this a bad thing? Well, if you have the right armor and have clearanced everything that should be, then no. However, I have left one of the most important items untouched and it's way overdue for a replacement. This would obviously be my cross member. The factory X member is weak and hangs below the frame rails. At the same time, the bottom portion of the transfer case also hangs below the frame rails. This holds me up. Some how, I have yet to have exploded my transfer case. In the wheeling trips I have had this year, I have managed to turn the factory X member into an upside down U shape, which actually lifted my transfer case above the frame rails. Still, the cross member hangs too low. In this next pic, I was denied from getting to the top of this rock, even after repeatedly slamming into it trying to bounce and slide the cross member over the rock....



So, where does this leave me? It leaves me wanting a completely-flat -to-the-frame-rails-cross member, one that is strong, and wanting my transfer case completely out of the way. So first, out with the old....





To do this cross member, I got a clocking jig



and some 2x6 3/16 wall



So after doing some measuring, finding the center, and how much material should be shoved up between the frame rails, I came up with this....









Using the center point, I kinda (yes, kinda) figured where the trans mount should go. I drilled holes and got this....



And this is where I leave you hangin' til I get some more work done!

Great job on the crossmember. Do you still have the dimensions from when you cut it out? How the hell did you get your bends so precise?

Sorry dude! Just saw the post. I don't have the dimensions but I will be doing a revision soon so I can get them now. The bends were easy. Basically, I just notched it and threw it in a vise. Bent it by hand until I was happy.

Great job on the crossmember
Thanks!
So how do you feel about that trans mount now that you've run this for a while? I am debating still between this and the way SFRautomotive made his mounts. I'm thinking I should get it as low as possible being at 4.5" (and maybe more someday).

'00 XJ not quite there..

As low as possible :confused: Do you mean as high as possible? You really never want to drop the t-case, if you get driveline problems it's a caster- and pinon angle issue, not a TC being too high ;)

Flat belly is the way to go :thumbsup:

Yes, down as in transfer case to crossmember relation. It won't be dropped really, since the new crossmember is actually pushing it up from stock location. I was just wondering if he has had any issues with his mount that way.

Haha I've got all kinds of current angle problems, trust me.

I have had issues with the trans mount being as high as it was. Actually, yesterday I have started another round of mods to the cross member. Stay tuned for pics of my flat cross member V2.0 :D

Cool! It's a lot if work, but well worth it if you can get it right. I think I may have to clock my t case this time though.

Your idea inspired us for this for our 4" lowered street jeep, 'becauseracejeep'. Gained like 2" of ground clearance. It is 2WD auto.

So I finally put that IRO jig to good use and clocked the base. Trying to fix the contact of the fan to the pulleys, I hacked the ***** out of the skid (no pics of that yet) and will beef it up a little too. Hopefully I'll have it complete this Friday.



Cut that useless piece off the case...

BUMP?! what's going on with dis

Just saw this post. Currently it's still holding and protecting my transfer case! However, it may be getting redone soon. I have a big piece of 1" UHMW that will probably be my new skid soon!
