Description

 

 

  •   This units fits all Jeeps 2003 to 2011 with the 42RLE automatic overdrive

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.

Features: The RubiCrawler increases your available gear ratios. This allows you to choose the appropriate gear, depending on the terrain in which you’re wheeling. Proper gear choice will allow you more control of the vehicle. Ultimately, this contributes to a fun, and safe, offroading experience, even in extreme environments.

Selecting the Proper Shifter for your Application:

The RubiCrawler’s shifting mechanism utilizes push/pull cable technology for a smooth and easy shift.  The universal cable shifter is included with the purchase of your RubiCrawler. (The universal shifter should be used if your vehicle is equipped with an Atlas transfer case) 

We also offer a twin stick cable shifter for the Jeeps.  These kits are designed to fit the stock TJ and JK consoles. 

The Jeep TJ's twin stick shifter replaces the standard hard linkage. We have designed a twin stick shifter that comes through the stock console for a clean installation that operates the RubiCrawler and the stock NP231 or NP241 transfer case. 

The twin stick JK shifter also provides a twin stick shifter through the stock console. This kit retains the stock transfer case cable with the addition of the new RubiCrawler cable. 

These shifters are an additional charge but are the best suited for most installations. (Note, if your vehicle does not have a stock transfer case, the universal shifter should be used.)

Rubi crawler Simple extra Gear Options (Jun 22, 2011)

by Woody's 4x4 from Vancouver, WA

  5/5
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.

Get a puller please! (Mar 09, 2011)

by Edwin Kloster from Wichita Kansas

  5/5
Last year I saw a Rubicon Jeep getting an Advance Adapters RubiCrawler.
It is a true bolt-in doubler that couples to stock Jeep transfer case.
Ratio possibilities with a Stock New Process 241 are 2.72:1 and 7.40:1.
As reported in advanceadapters.com.

Looked around to find out more about it, deals shipping, prices. Found discount and free shipping.
Asked around forums friends got about 50% rating. Man I'm I so glad I went 100% for Rubi-Crawler Planetary Crawl Box.
