Got my 4.56's installed last night by McDirt from Dezertrangers.He did a great job and really knew his stuff.Very happy with the outcome,Cant wait till there broke in so i can really see what it will do.
My truck has 4.10's in it and I had 32's and It was probably just about like a stock truck with 3.73's. The only time I wished it was geared a little lower was when towing or wheeling. There was a lot of parasitic loss with the 4wd. Now that I have 33's its even worse. I cant wait to put the 4.56's and locker in this summer.
He will charge you $200 labor for the rear and $350 labor for the front ($150 more becauses it has to come out to be regeared). Bring your own gear sets and install kits.Pm me if you want his contact info. If you do come down let me know well make a mini meet out of it.
