my results say its a 4.11. it could be right i guess, but this truck has never be able to spin the tires much, and its a bit of a dog off the start. the power of the motor should be enough.. on the high way i run 70mph at 3000 rpm. 16 inch rims. Tire size 235/85/r16.

does this sound like a 411 to you? btw its an open axel.
