Advance Adapters RubiCrawler reduction gearboxes are essentially 2-speed planetary transmissions that offer a direct drive, plus a 2.72:1 drive. These heavy-duty aluminum-housed units replace the stock 42RLE tailhousing and bolt directly to the stock Jeep transfer case, or an Atlas unit. These true doublers allow you three low-range options: stock regular low range, 2.72:1, and the combined total of the two for extreme crawling. Going down long steep hills goes from hair-raising to relaxing, and rock crawling is much smoother. Choose the proper gear for the trail and enjoy the ride using an Advance Adapters RubiCrawler crawler gearbox.
