This is a Crawl Box Unit for all 1988-1995 3.0-liter 3VZ-FE 4WD applications. This unit is installed between your V6 5-speed or automatic transmission and a top shifting 23-spline gear drive transfer case, not included. Because this is designed for V6 applications, we will only build it using 23-spline components. You have the option of a 2.28:1 or 4.70:1 low range gear ratio.

All necessary hardware included. Includes factory shifter assembly with a Marlin Crawler Turtle Shift Knob Unit. Floorboard and drive shaft modifications are required. No core charge.

Please note you must use a 23-spline transfer case to go behind this 23-spline Crawl Box. This requires a special 23-spline input that Toyota only manufactured from 1986-1987. If you do not have a 23-spline input, then please consider our high quality 23-spline input made from Chromoly steel and featuring our Total-Spline technology. This is the strongest 23-spline input in the world.
