As the title says; with my AX-15 to D300 clocked up to almost flat; it looks like I can save almost 3" of belly fat; and my OEM skid seems to have a bit of "wobble" with the current mount. Looking for something heavy duty.

These are the two I've found so far:

https://www.tmrcustoms.com/universal-transmission-transfer-case-crossmember-mount

I like the look of the 1st one a little better; but the price of the second one.

Any other reccomendations? Thoughts?

If you have time, I can check to see what my builder did this coming week. I had the traditional mount on it, but he picked something up and incorporated it into the skid plate. Probably towards the end of the week?

I'm happy with it. I just needed to clearance the front lip a little to clear the exhaust and the front driveshaft. You may not have to do that depending on exhaust routing and amount of lift etc.

Can you snap pictures?

I don't think I can go flat (not that tucked) but I think 2" is too much; which one did you use?

I suppose I could go flat and put 1/2 or 1" spacers in on the frame mount..... The 2" may be closer than I think.....

What mount did you use? Pics would be cool. 😁

The previous owner of my Jeep swapped in the ax15 but didn't clock up the tcase. I'll be looking to do something similar as you guys.

This is what I did when I swapped in an AX15. I am using the Novak adapter/clocking ring between the AX15 and Dana 300. I was able to reuse the stock transmission mount, torque arm plate and bushing assembly, and only had to drill three holes in the OEM skid plate. Starts around post #1264:

I am using the stock skid plate, with whatever drop it has built in. I did not want to make a "flat belly", I was worried about drive line angles and floor pan interference. I need to cut off the OEM skid plates "bulge", and I will gain a bunch of clearance :twocents:

Not sure if this is what y'all are looking for. It has held up fine for me for over 10,000 miles of on/off-road usage. I am running a 4.0. Best thing, all stock parts that did not cost me anything, and I only had to drill three holes in the skid plate.

I have RE-used my stock one similar to yours when I did the 4.0/AX-15 swap, but mine seems to have a bit of “bounce” or play in it - haven’t studied it well to determine where it’s coming from..... Are you just going to plasma out the “hump” and weld a flat piece in?

When I clocked my transfer case up halfway, I did cut the bulge off of the skid plate. I welded a piece of flat steel in its place and have run it that way for years. No problem and I gained some clearance.

Yes, that is on the to do list, cut the hump out and weld in some flat steel.

I am running polyurethane transmission and motor mounts, I can not find quality rubber mounts anymore that last more then a month or two. Especially on my tan Scrambler, 350/700R4, I would get a few weeks out of rubber transmission mounts :eek:

On the skid plate, a few years ago when I was working on Josh's tan 1981 Scrambler (factory 258/auto), I noticed that the OEM skid plate on it was almost entirely flat, no hump, kind of like a Dana 20 skid plate. If I could find one of these skid plates, I would just swap it on, no modifications necessary :thumbsup:

I just pie cut the middle of the hump by eye and beat it flat before welding it back together. Cost me a little bit of grinding wheel, welding wire and gas. Ended up trimming a little off the end of the reworded hump for driveshaft clearance.

Easy to do until you source something else. :shrug:
