I think that was used in the original version and was revised later on.

Nice, didn't realize the instructions were even out of date for the late "original model"

Yep, the "newer" original skids definitely had some changes from what is in those instructions.

For those of us now there are still not instructions,nothing's changed there, not a big deal, but a hardware list would be nice, especially for someone like me that is building my jeep where I had space to do so, so retrieving missing hardware is an hour round trip back to town, frustrating

So I installed the C-channels and crossmember yesterday (which I will be removing in order to modify). The website states "Some trimming of the cross member may be required for some TJ models" on the Modular Under Armor page. I found out after the install that means us non-Rubicon guys with the NP231 transfer case (directions would have been helpful there).

But the question I have for anyone running this mod is has it caused your Jeep to overheat? I took it for a quick test run after installing all the structural pieces (no armor) and everything seemed fine. However, I took it across town today, got stuck in some traffic, and got the "check gauges" light and tone. That's when I noticed the temp gauge way over in the red. I pulled over and found an empty parking lot where I drove around in large circles with the heat on. That actually cooled the engine down rapidly. I didn't lose any coolant and I was able to drive the remaining distance of my trip with no additional issues. It's late at night here now so I haven't done any investigating of my coolant system, but has anyone ever heard of any tummy tuck causing this issue due to the reduced airflow around the transmission and therefore transferring heat to the engine block? I suppose it could be a total coincidence and I'll start troubleshooting the coolant system first, but this was actually a concern I had while performing the TT install and now here it is. Anyone have any input? Sorry if this topic has been addressed elsewhere. I attempted to search for this issue but couldn't find a related thread. Thanks.

Nope, your cooling issue is coming from elsewhere. Never had an issue with any of the plates I've had on my rig and never any other issues on any other rigs.

We had no cooling problem on our rubicon with the larger transfer case blocking air flow

Your cooling fan isnt hitting the shroud keeping it from turning freely is it? Sometimes after moving the driveline around adjustments have to be made to the shroud to keep everything happy.

That was my thought too, I bet your shroud and fan are pressed up against each other hard.

x3; after installing the crossmember I had to move the fan shroud down a bit further to keep the fan from contacting.

x4 but I didn't learn this until I was in the middle of the desert.....I thought after most of my research before installing my savvy under armor that i wouldn't need to adjust the fan shroud if I went with a body lift and mml...boy was I wrong....as far as the crossmember needing to be trimmed I had the same problem with mine......when I spoke with gerald about it he said they were going to modify the crossmember so that wouldn't happen.....I guess that hasn't happened yet.....

You are all correct. I just got home from work, popped the hood, and the fan is firmly pressed up against the lower portion of the fan shroud. I took for granted that the MML would compensate for this. I checked the oil, it doesn't look like chocolate milk, so that's good... I'm actually pretty impressed that the engine remained cool for the remainder of the drive considering the traffic hadn't gotten much better by the time I got back on the road and I was basically driving with no cooling fan. Now my concern is potential damage that may have been caused to the fan assembly. I'll read up on some of the overheating/cooling system threads.

I would think that worst case as far as the fan is that you may need to replace the clutch.

Be very careful with the wife mod. Uninstallation can be extremely expensive. Wife mods have been known to take the Jeep and all other mods during the uninstall process. Also, make sure you service your wife mod properly as often as humanly possible. Wife mods not properly serviced may malfunction or uninstall themselves at any time.

So I removed the shroud and the fan spins freely by hand. Hopefully that's a good sign. As far as my options now... I could trim/relocate the shroud, but I actually have a set of Brown Dog MMLs that I ordered prior to the Savvy UA (I didn't realize the MML spacers were integral to the UA system when I started planning for the TT). So my next question is, does anyone see a problem with adding an additional 1" of lift at the motor mounts? I mean the fan is contacting the lower portion of the shroud - lifting the engine an additional inch should solve that problem. Does anyone believe that a total of 2" of MML is a bad idea. I hadn't really considered how much the engine would pivot forward after raising the transfer case 4", but the answer is evidently 2". I know installing a set of after market motor mounts on top of 1"MML spacers is a lot of work to avoid modifying the fan shroud so I may not go with this option. Just wondering if anyone already knew any reason why adding an additional inch of lift at the motor mounts would be a bad idea. Thanks!
