NEW! ONLINE CATALOG Clicking on each drivetrain will open a larger image in a new window The Advance Adapters "Atlas II" 3.8:1 Ultra low gear-driven transfer case is the ultimate gearing solution for combining both on and offroad performance! With an Atlas equipped 4WD, you have the opportunity to select a sensible ring and pinion gear ratio for great street performance and strength. Combined with a low-geared crawl ratio of your choice, you now have the ultimate combination. This allows you to compete with the most well equipped offroad vehicles, yet cruise comfortably down paved roads. The 3.8:1 Gears "The Ultra Low" unit gives a definite advantage when replacing a Jeep New Process chain-driven transfer case by allowing an additional 6 inches of rear driveshaft length for a drastically improved rear drive angle. The Atlas 3.8 is a good choice for the avid 4-wheeler, since this low gear ratio is ideal for moderate to occasional extreme rock crawling.
