Dana 300 Transfer Case Twin-Stick Shifter Kit

The Dana 300 is a very good recipient for a twin stick conversion. This kit comes with the hardware and instructions required to create a clean and highly functional shifter upgrade.

Product & Features

Our high quality standard shifter is more simple and elegant in its design but lacks adjustability.

Block_TX300

Allows for forward and backward length adjustment that is often advantageous in swaps where the transmission is longer than the original to keep a more stock transfer case shifting location.

The kit comes with all the hardware required to convert to twin sticks.

Procedural Requirements

The TX300 kit uses the factory shift rails within your Dana 300. Installation does not require disassembly but not all positions listed are available; the normal single stick positions are. For fully independent axle operation, disassembly of the Dana 300 will be required. This is an excellent time for a rebuild of your Dana 300 or at the least to seal up any leaks.

To clarify, both of these shifters are completely functional without removing the interlock pills. You get a cleaner and easier shift of each rail independently rather than forcing the rails though a pattern with one stick. Removal of the interlocks simply allows all of the positions to open up and be available.

A commonly asked question - “Is it possible to lock the transfer case by putting one axle in low and the other in high range?”

Answer – Yes, it is possible but your really have to try to do it. The result is not unlike a drag race transmission trans brake where they engage two gears at once to hold the transmission while staged and then one is let go to launch the car. You will have a lot better feel with the twin sticks and lack of linkages.

We highly recommend this shifting method.

As to shifter positions, the low-range positions are all the way forward and the high-range positions are all the way back. Neutral is in the middle.

Applications & Compatibility

These shifters work with all Dana 300 Transfer cases. For full availability of all of the positions, the transfer case must be disassembled and the interlocks removed.

Dana 300 Billet Bottom Cover Pan

Dana300pans.png

These rigid and precisely machined billet bottom pans are the answer to a few Dana transfer case dilemmas. The thick, smooth-finished flange replaces the thin, warped factory pans and they virtually assure a drip-free seal.

Two designs are available for the Dana 300: The shallower depth, low-profile version for Jeeps requiring greater ground clearance. This version increases fluid capacity over the factory pan by about 6 oz. The extended depth version that maximizes the fluid capacity for the most punishing service. This version increases fluid capacity over the factory pan by about 16 oz.

 
 


Installation Requirements

Basic installation is quite simple requiring only normal mechanics tools. Depending on tunnel clearances the transfer case may need to be dropped a bit to allow the bolt through the tower.

To fully realize the advantages of a twin stick setup and all of the available positions you will need to disassemble the transfer case. This is the perfect time to do a rebuild using our superior kits with stronger center pin. At the least you will want to replace seals and gaskets if performing this option.
