Product Details

The Jeep Dana 20 transfer case is a strong, compact transfer-case. However, the rear output shaft is not as strong as it could be. The 1 1/8-inch 10 spline stock rear output is known to be weak and is no match for lower gears, big tires and V8 engines.

We offer a heavy duty tailhousing kit for the Jeep Dana 20. This kit features a new 1 3/8-inch 32 spline rear output shaft, 356 T6 heat treated aluminum alloy tailhousing, shims, bearings, fastening hardware and detailed instructions. This kit is extremely simple to install and you can even do it with the Dana 20 still in the vehicle!!!! The new speedometer drive housing (not included, but available separately via pull-down menu to the right) gives you the advantage of calibrating your tire and axle gearing. Due to this feature, our tailhousing is 1.5-inch longer than stock -- driveshaft modifications are required.

**For speedometer gear drive, see second image above.  Select drive based on axle gear ratio and tire size.

**Note: Yoke Nut is NOT Included.  Original Speedometer Drive Housing will NOT work with this kit (the new one in the pull-down menu does work with this kit).

**Note: these are assembled to order, and may take 3-10 business days or more to ship out.  Contact us for more details.
