ya, you got it domes, 22-24mpg,

you have that extended cab so those 4.10's will be great, i run about 2K rpms at about 60-65, i can't remember.

it will be a badass upgrade, but you'll loose that 2nd gear downshift on the highway, i used to love that gear, going about 70 and drop that bad boy down into second, it would scream all the way up to about 105, now i have to use third and build the speed up, second it good for around a 55mph drop downs.

but , being a truck, i like the quick launching.


have fun,
