I have just bought this truck two weeks ago and found out that the speedo is way off according to 2 different GPS systems. The truck is a 2003 1500 reg cab 4x4 with 3.55 gears running on 315/70/17 BFGs. It is about 6 to 7 mph slow. How hard would this be to fix? Wanting to lift it this fall if I am physically able to. Any advise on lifts is also welcomed. Thanks

Can't help on the lift, but a dealer should be able to flash you computer for the larger tire size and fix your spedo problem.

just go in and tell them to set your tires revolutions per mile at 604, will cost between free and 80$, depending on the dealer
