Although I haven't as yet had the chance to test my 2003 dually in deep snow, I have driven it on ice. With one side on ice, and the other side on dry blacktop, I noticed no slippage when starting. FINALLY A FACTORY LIMITED SLIP DIFFERENTIAL THAT WORKS!!!!! On my previous trucks, I always felt like I wasted money by ordering a limited slip differential in the Dana rear axles. So, I suspect my limited slip dollars will finally pay off when "Big Red the Second" does encounter deep snow. I believe the new American Axle limited slip will definitely help offset the dually traction disadvantages! DODGE TURBO-DIESELS FOREVER!!!!!
