So Im starting to look into setting up Dual T-cases. I have the 3.0L which means that I have a chain driven T-case. I know that marlin has an adapter so that you can run a gear driven case in front of the chain driven, But then how does the gear driven case link up? Also I have heard that there are adapters that will link up 2 gear driven cases to the tranny. Basically I just want to know what people are running for their setups and where I can find more info.
Thanks for any help

Installing a dual transfer case into your 3.0L V6 truck can be done in two ways: 1) By using two gear driven transfercases, you can replace your stock Chain Drive transfercase with a Gear Driven Dual Case Transfercase. 2) By using one gear drive transfercase low range Crawl Box, a 100% bolt-in Dual Case Unit can be installed between your factory transmission and factory chain drive transfercase. We have been using the Gear Drive Transfercases and its components for over ten years and have found them to be most reliable. We believe that a 1979-95 Gear Drive Transfercase is stronger than a 1988-95 Chain Drive Transfercase. The biggest problem with the Chain Drive Transfercase seems to be with its input gear, which we have seen fail.
The Chain Drive Transfercase uses a 2.56:1 planetary gear reduction, which, due to reliability concerns, we do not offer lower gearing options for. With this said, a Chain Drive Dual Case setup is limited to the addition of a 2.28:1 (or 4.00, 4.70, 4.97) MC10-R10 Crawl Box. A combined Reduction of 5.84:1 is standard and a 12:1 is the optional Ultimate setup using the 4.70:1 ratio (please note that the 4.00 and 4.97:1 gear ratios are generally not recommended).
The Gear Drive Transfercase uses a standard 2.28:1 gear reduction, and may be swapped for a 4.70:1 (or 4.00/4.97 if desired). When combined with our Gear Drive Dual Case Unit of 2.28:1, a standard combined reduction of 5.19:1 is achieved while a 22.09:1 is the optional Double Ultimate setup using two sets of 4.70:1 gears, something that is NOT possible in a Chain Drive Dual Case Setup.
Floorboard and drive shaft modifications are required, while the factory crossmember is retained and remains in its original position.

Alright I understand the gear reduction and the advantage of having two gear driven t-cases, But what would I need to do to mount them to my transmission? would I be able to get a clocked adapter as well?
Thanks

Marlin makes the adapter for that.

What you really need to do is get ahold of MC, let know what your plans for the rig are, and they will steer you in the right direction.

I love Marlin but is anyone running something besides marlin adapters?

I believe AA and Inchworm both offer adapters.

Besides those three companies, no one else that I know of makes them.

marlin is the best.

Did you get your front locker in?
