Description: The Atlas II is available in four configurations. 3.0:1, 3.8:1, 4.3:1 and 5.0:1. The 3.8:1 ratio is recommended for those with automatic transmissions as the 4.3:1 and 5.0:1 are so low the stock brakes would not be able to hold the Explorer back at an idle. With a manual transmission this is not a concern because you can simply disengage the clutch and come to a complete stop.

Pros: Low gearing for unstoppable rock crawling
Cons: Price is steep, but the product performs flawlessly

Ever since I grenaded my stock transfer case back in '96 I was looking forward to a heavy duty replacement for the BW 13-54. The 13-54 is a light weight chain driven unit which does fine in all, but the most extreme off-road environments.

I have been using my Atlas II for several years now. All I can say is WOW. Actually I can say more. The low 4.3:1 lowrange is extremely impressive while rock crawling. No longer do I have to smoke my clutch while trying to finesse the Explorer over boulders. Now it just crawls.

This deep of a low range isn't for everyone. You give up speed on the trail (at least in low range, high range remains the same) for extreme torque and throttle control. The manual transmission is much easier to control on obstacles with the deep low range. Rock crawling has become a pleasure instead of a chore. Let the clutch out slowly in low range and get ready to move without the need for slipping the clutch. Obstacles which used to require revving the engine and slipping the clutch are now accomplished with no slippage at all.

On the highway, I immediately noticed the lack of backlash that was present with the stock chain drive case. It also feels like a few extra horsepower have been freed up. This could be due to the gear to gear design and the use of bearings throughout the case.

Shifting takes getting used to, but once you learn the system it's extremely easy and has a very positive feel. From the look and feel of the unit I believe it's going to be an excellent long term investment.
