I have an 2006 f-250 super cab with 6.0 and 4X4 with a 3.73 rear end.
I am wanting to increase the towing capacity of my current truck. Looking at the towing charts for 250, 350 SRW, and 350 DRW, the only difference I see is the rear axle. The engine and transmission are the same I believe. (Correct me if I am wrong.) Is there an aftermarket axle that I can buy to increase my towing capacity? I do realize that the towing limits are not just dependant on the engine or transmission. Buying an axle is cheaper than buying a new truck (I hope).
