Note: Transfer Case Clearances. There is no ‘magic’ to gaining ground clearance. The significant

ground clearance gains that the Tummy Tucker skid plate provides are accomplished by ‘tucking

things up’ by reducing some of the space between the floor pan, powertrain (trans and t-case), and

the skid plate to the bare minimums (usually ¼ to 3/8”). To do this we have designed several

different application-specific TT’s, but even with this level of ‘custom fit’, the substantial factory-build

variation from one Wrangler to the next may cause you to encounter ‘touch’ conditions that require

minor adjustments – these are your responsibility to correct as Nth° has made every effort to assure

that the TT will fit perfectly on the Wrangler years and models it was designed for. Be especially

aware that the frames of ’03-‘06 TJ’s are extremely variable in dimension compared to previous

years, with brackets and holes that can be significantly out of position compared to Jeep’s own CAD

models (which were used to design the TT). There is an appendix of solutions to known issues that

have been encountered in a few cases.

Also - if everything is adjusted properly - you should not have any contact issues during normal

driving even though clearances around the t/case are reduced with the TT. Do not drive your Jeep

with the t-case rubbing either the floor or TT for extended periods – trans or t-case failure may

eventually result! Unless you are using enough body lift, installation of a Tummy Tucker on a

Rubicon TJ requires floor modifications (see table in step 4).

Kit Part Numbers

TT14021 (Rubicon TJ/LJ with manual trans)

TT14031 (Rubicon TJ/LJ with automatic trans)

Vehicle App’s

‘03+ TJ Wrangler and Unlimited Rubicon models ONLY

The frame rails are unmodified in the area of the stock center skid plate.

Any lift kit being used does not require center skid plate-mounted control arms.

A double-Cardan (incorrectly aka ‘CV’) rear drive shaft is installed and the pinion

angle adjusted for use of this drive shaft via a Stinger or adjustable rear control

arms, etc. (If you have ZERO suspension lift on your Rubicon, you can use the

stock driveshaft).

An original Rubicon transmission is used: NV3550 (5-spd. manual), or 42RLE (4-

spd. auto.)

Assumptions

Equipment that must

already be present

on your Wrangler

The standard-for-Rubicon NV241J ‘Rock-Trac’ transfer case is used.

Floor jack and ~12” piece of 4x4 post (or vehicle lift with a tall jackstand)

Set of Allen ‘hex drive’ keys (including 8mm).

Long pry bar or equivalent (autos only)

Required Tools

and Equipment (in

addition to common

hand tools)

Ratchet Strap, rope, etc. (see step 4)

NOTE: If you have anything other than a ’03-06 TJ Wrangler Rubicon with the original trans and

NV241OR ‘Rock Trac’ t-case, you have the wrong instructions (make sure you don’t also have the wrong

TT!). To install a special TT with an NV241OR t-case in an older Wrangler, you need to follow the

instructions for your model year and can follow step 4 of these instructions to perform the required floor

modification if not using a body lift.

Please take the time to read these instructions completely before beginning – they are long because we

want you to get the installation right the first time with no unnecessary delays.

Do not start or attempt this product installation if you are unsure of your abilities or do not have the

resources listed below. If applicable, be sure to have all welding done by a certified person, and

check/set all specified torques with a torque wrench…too tight is not just right!!

Step 1: Unpack boxes; Check contents against packing list; Verify parts in good condition. Be

especially sure that you have the right parts for your application!

Step 2: Read all of the following instruction steps before beginning! Do not disassemble vehicle unless

all parts are present and all tools and facilities required are available.
