This reduction unit replaces the stock 42RLE tailhousing with a 6 gear planetary reduction box featuring a 2.72 low range. This is a true, bolt-in doubler that couples to the stock Jeep transfer case or an existing Atlas transfer case.

Thanks for the Great Product and the new twin cable shifters for the TJ work awesome. Install went really smooth with no issues. Customer had np231 and went to a np241or from a rubicon but did not want to lose his regular low range. This made keeping the original and getting the extra final a bonus. Highly recommend to anyone.
