I was just wanting to see if anyone on here has the same setup I'm about to have... Single cab, 5.2L, with 3.92's. I'm wondering what kind of gains I'll get in overall performance, plus what kind of mileage I should expect. Any input would be appreciated.

 

Worse mileage highway. Better acceleration. Etc. Although I think you're only gonna lose 1.5mpg... Not sure on that though... Maybe less. But it won't help mileage on the highway.
