Default Klune-V Underdrive Crawl Box - $900
Klune-V is an Extreme Underdrive gearbox that bolts in place between the transmission and transfer case. It multiplies your existing gear reduction by up to 4 times, rather than a usual underdrive of 1.2 times, or so. It is intended for extreme four-wheel-drive applications. It works equally well with both manual and automatic transmissions. This is the 'Goliath' model.

The Klune-V Extreme Underdrive's multiple low range provides the most versatile gearing set-up available. If your vehicle is fitted with the "Goliath" Extreme Underdrive, you receive three different Transfer Case ranges:
Normal High Range
Normal Low Range
An additional "crawl" range * 2.7 TIMES AS LOW AS YOUR EXISTING LOW RANGE

I was going to use this in my Jeep TJ 4 cylinder when I stretched it, but I sold the Jeep.
It has a 21 spline input shaft and a 23 spline output shaft.

Fits Jeep TJ 4 cylinder SE model or any other 21 spline input shaft transmission
