This is a great question that I hope someone with actual experience in the swap can respond to. I have a 1500 with 20" wheels, 3.0 diesel and 3.55 rear end ratio and have been considering this same swap to 4.10s. It tows good now and I know it will tow better but having some specific feedback from others who have done the swap would be great. I'd also like to hear about the cost the dealer charged for this. I plan to buy my own gear set. I don't mean to steal your post only to add that others have the same questions relating to this same set-up.
