Trail Creeper 2.28 x 4.70 Dual Transfer Cases. If a 4.7 to 1 transfer case gear ratio has proven insufficient for the type of offroading that you want to do and you look forward to the kind of quality time with your tools that modifying your floorboards and drive shafts would require, it’s time to upgrade to a Dual Transfer Case setup.
With a stock 2.28 transfer case, a 3.93 first gear ratio and 3.90 differential, your crawl ratio works out to 35 to 1. The Trail-Creeper 2.28 by 4.70 Dual Transfer Case changes the crawl ratio in that scenario to 164 to 1! That massive torque and fine control certainly changes the game, enabling you to take on terrain that others fear to crawl.
The Dual Transfer Case will work in 1979-1995 Toyota Pickups and 1985-1995 4Runners as long as they use one of the transmissions described in the Transmission Matrix below. We manufacture 12 different variations of this magnificent unit. Choosing the right variation for your application requires defining the Input Gear, Shifter Options, and Stick. Input Gear options are 21-Spline or 23-Spline.
In the Dual Transfer Case the front reduction box that connects to the transmission needs to match the Input Gear of your transmission. V6 and 4-cylinder turbo trucks use a 23-spline input, all others use 21-spline.
In the Dual Transfer Case, the rear reduction box connected to the front and rear output components is always Top Shift. The front reduction box that connects to the transmission in most cases should match the shifter configuration of the transfer case it replaces.
Find your specific transmission in the Transmission Matrix below and look under Shifter Options for the specific shifter configuration of the stock transfer case. Single or Twin Stick options are Single Stick Only or Twin Stick Ready Loose Interlock Pin. A twin-stick allows independent control of low or high range and 2 Wheel Drive or 4 Wheel Drive engagement.
With a twin-stick configuration you can switch between 2 Wheel Drive and 4 Wheel Drive without stopping and access 2 Wheel Drive Low-Range for better handling when traveling between obstacles on a trail.
In the Dual Transfer Case, the rear reduction box connected to the front and rear output components can be either single or twin stick, based on your personal preference. Installation will require significant floorboard and driveline modifications to fit! The front driveline must be lengthened and the rear driveline shortened.
