Hey guys i dont post here much but i'm starting to mod my truck a little now...I have an 05 crew cab 4x4...i picked up a complete front diff with 4.10's and i pick up my rear ring pinion and install kit tonight. I'm guessing i'll see quite a difference in the behavior of the truck with these gears. I have a wait4me tune and going to have him send me a reprogram for the gears, i plan on doing long tubes in the spring so i'm waiting on a full dyno tune at my budies shop. This truck is my daily driver and work truck (own a lawn care business). I'm trying to think of what else i can do to it to make it a better tow vehicle without selling it and buying an HD!
