Tummy Tuck & SYE Questions

Just curious as to everything needed to do a tummy tuck on your jeep, I'm disliking the transfer case drop more the more I look at it, I understand you need an SYE kit, but after that how do you get it tucked up there? Obviously a flat skid plate and body lift, but where can I get one of these kits

I just did my "99" and used a Undercover Fab Works high clearance skid. They come in both steel versions and aluminum versions. The aluminum is really nice, but also double the price. Under Cover Fabworks, LLC - Transfer Case Skids I did have some fitment problems, but it's related to the older model TJ's...yours shouldn't be an issue. Along with the skid you should do the Lowpro transfer case mount, a Novak tc shift cable, small body lift (1") and a 1" motormount lift. I really like the belly clearance I wound up with.

In addition to the SYE and DC driveshaft, I also needed the following in order to make everything work:
  • Adjustable rear control arms, upper and lower
  • Rear track bar relocation bracket
  • Rear adjustable track bar

I got my SYE and shaft at Tatton's. Great kit!

The best SYE on the market is the JB Conversions unit. Quality shafts, may be purchased at Tom Woods, Adams or Tattons.

Tom Wood's (Tom Wood's Custom Drive Shafts - Tom Woods Custom Drive Shafts Custom Driveshafts Specialist) is known for their customer service .

Parts needed:

SYE-JB or Teraflex either will do
Rear drive shaft
Adjustable rear upper control arms
Angled track bar bracket or new rear track bar
Belly up-I recommend UCF ultra high
Low profile tranny mount
Novak shift cable
Body lift
MML

I think that should cover it. It is pretty expensive to do it the correct way.

That's a great list. The one thing I had to add were rear lower adjustable control arms to bring the rear axle forward enough for the track bar to miss the gas tank when adjusting pinion angle. Part of the reason for that may have been that I had longer than stock rear lower CA's on there that had come with my original 4" lift.

I hope it is a good list as that is my exact list. I did not need new lower control arms as it barely missed my gas tank skid, but I do have a Savvy skid so that may make a difference.

you can get both from Tom woods, I have a AEV tummy tuck, Its the highest lift out of all companies. I have and auto all i had to do was put in a bracket to lower the fan shroud. If u want to just lift up the mounts get a 1in motor mount lift. as for the rear... you need adj upper control arms im still getting away with the track bar relocation bracket but u will need an adj rear track bar. tom woods has specs on every combination of a tummy tuck company. all they need to know is year lift, what diff you have and the current messurement from yoke to yoke.
I would go with UCF they are alot cheaper and you can choose how high of a TT u want.
this is mine with the AEV tummy tuck and full adj control arms all around

I think my tummy tuck is one of the better mods that i have done. I went with the Teraflex skid, and I am happy. It has a forward rake to it to help "slide" over obstacles. it is about an inch worth of rake. I gained a total of 2.5 inches over the stock skid.

I also recommend all 4 adj arms. In fact I recommend all 8...but that is a lot of dough and it took me a year to save up for all 8 and the TT.

Love the clean look with the flat skids, I'm sure the benefits are great offroad too, extra clearance and less shovel like.....some day!

Best mod for a TJ in my opinion. The UCF ultra high clearance in aluminum is worth every cent.

Agreed...love how clean it looks with a TT

Aluminum UCF plate here. Absolutely love it.

Nothing like being on 33's with 2" of lift and watching a rig with 35's hang up behind you. It is definitely my favorite mod.

Also, not sure where you are at in Florida, but UCF is right here in Dothan, AL. Might be able to save yourself from shipping charges.

You shouldn't need U-bolts. The double carden joint should have a built in saddle that just bolts up to the yoke on the SYE. The saddle holes should be threaded. I don't remember who provided the bolts for mine, but I think they came with the Tom Wood's drive shaft. (it was either that or they came with the JB SYE). Here's a sample picture

The one thing I did have to do was grind down the sides (shoulders) of a wrench (I think it was a 13mm) because of the limited clearance on the yoke.

Once you lose the fat belly, you'll never look at those stock t-case skids the same again. They'll stick out like a sore thumb, especially when dropped further down than stock.

I'm hoping to do this come spring. I've been reading on Savvy's site, because I'm thinking that's the better way to go VS going Rokmen.

And to be honest, I've been totally confused why you need a MML. But I'm still researching.

You don't 'need' one.

First reason it makes sense--you 'need' a body lift to provide enough extra clearance to tuck without interference between the transmission/t-case and tub. Raising the motor up 1" takes care of the fan shroud/fan alignment issue.

Second reason it makes sense--driveline angles. Do everything in your power to reduce the angle between the t-case output and drive shaft.

Third reason it makes sense--the drivetrain (engine, trans, t-case) is a straight line. Raise the rear of it (transfer case) so raise the front of it.

Fourth reason it makes sense--in Savvy's case, the engine skid uses bolt bosses in the motor mounts as the support connections.

That makes sense.

Would you be interested in helping me out with that when I'm ready?

Of course my man. As long as you don't want to try to swap in a manual trans.

I kid, I kid.

For those that are looking into a tummy tuck, check out Barnes4wd. I run their skid and it's 1/4" of pure steel beef. It takes a little more to it due to the fact it's set up as a universal piece for those that do engine/transmission/transfer case swap, but it's beyond affordable. Link below to their website.
