Advance Adapters Saturn overdrive units make great additions to older Jeeps and International Harvester Scouts with Dana 18 transfer cases. They offer the needed gearing that those vehicles were lacking, plus the fully synchronized feature allows for shifting on the fly. Advance Adapters Saturn overdrive units can handle up to 300 lbs.-ft. of torque—well within the range of most stock engines. More product features and benefits include: * Originally designed and developed by Warn Industries, Advance Adapters purchased the tooling, engineering data, and inventory from Warn Industries in 1991 * Advance has incorporated a few upgrades, but they are all still interchangeable with the original Warn overdrives * Will install directly on the backside of the transfer case through the inspection cover * No cutting or modification of the drivetrain is necessary, with only minor modifications required to the floorboard for the shifter * No relays or electrical connections needed * Shifter linkage and handles sold separately

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.
