I am about to put the 3" procomp standard kit on my truck. I'm also about to get the 15"/10" (3.25"backspacing) wheels and 33"/12.5" BFG all terrains. I've decided that i'm going to swap my stock 3.55 gears because I think that they would be alitte high for 33's. I have decided on 4.10's because i think 4.56's would be alittle low. I am eventually going to add a 3" body lift and repace the 33's with 35's and I think that the 4.10's will work just fine with the 35's too. What i need to know is what all the gear swap will involve. Has anyone priced a basic gear swap? What all parts will i need to buy? How much will labor be? How much will the actual gears and parts be? How long will my truck be in the shop getting the gears installed? What is the total price i'm lookin at?
