Rubicrawler - New Jeep Wrangler Low Range Crawl Box

Advance Adaptors is getting ready to roll out a rad new product for Jeep TJ & JK Wranglers with the 42RLE auto tranny. It replaces the tailshaft portion of the 42RLE with a 2.72:1 planetary low range box. It looks like its designed to keep your drivetrain the same length as stock, minimizing any changes to driveshafts and tranny mounts. No word on the exact release date other than "Winter 2008". Theres also no word on pricing, but I'd imagine they'd set it below the atlas to make it an attractive option.
Here's what AA has to say about it....

"Jeep TJ & JK owners with the 42RLE, 4 speed overdrive automatic listen up! Do you dream of having multiple 4wd low ranges just like the latest and greatest after market transfer cases without having to sacrifice your bank account or prep your Jeep for some major retro-fit surgery?
Advance Adapters is proud to release the Rubi-Crawler. This new reduction unit replaces the stock 42RLE tailhousing with a 6 pinion planetary assembly featuring a 2.72:1 low range. This is a true bolt-in doubler that couples to the stock Jeep transfer case or an existing Atlas 2 speed."

Here's an artists rendition of what it may look like when installed and operating.....

RubiCrawler Update
The Rubicrawler is still progressing as planned; we have finished the new input gear, gear selector slider and output shaft. The prototype housings and the planetary components are ready to be installed. The last piece of the puzzle is the shifter mechanism and the shifting linkage. Once the shifter is finished, we plan on running one of these units in our Jeep JK. If all goes well in this vehicle production will begin with having permanent molds made for the RubiCrawler housing. This should be around the time of January 2009.


RubiCrawler facts:
We still are planning on having one of these units at the S.E.M.A. show this year in Las Vegas.


We still do not have a complete price as of yet; however, we are taking orders for these units to hold your place in line. The order is just a way for us to determine how many components to make for the first run of parts. We will advise you of the price when available and allow you the option to keep the order active or to cancel the order. No money is required to initiate an order.




We plan on offering two types of shifters for the RubiCrawler. One will be a simple single handle cable shifter, and the second will be a cable shifter integrated into the TJ and JK consoles. This second style shifter will be released mid to late 2009.


The RubiCrawler part numbers are 42R023 for Jeep TJ’s and 42R023JK for JK’s
