JK Jeep RubiCrawler
A true bolt-in multiple low range gearing solution for Jeep JK equipped with the stock 42RLE four speed automatic transmission.
The RubiCrawler is an auxiliary gear box that replaces an empty rear tailhousing used to facilitate the mating of itself to the factory Jeep NP231, NP241 or NP241OR transfer cases.
By using a new cast housing that adheres to factory dimensions the RubiCrawler creates an optional low range gear and the ability to double up the factory low range.
Available with a standard shifting system or for those who are concerned with the factory interior look of their vehicle, Advance Adapters have developed two integrated shifting systems for use with the factory transfer case and console.
Note; JK Jeep RubiCrawler kit will only fit the stock 42RLE four speed automatic transmission.
