Changin Gears

Hello Gentlemen,

How are ya? I want to change my gear ratio and add a locker in the rear when I lift my truck in a couple of months. B/c it will cost so much for the lift, tires, wheels, etc., I am only looking to add a locker and gears in the rear end for now. My truck came stock w/3.73 gears. Am I gonna screw anything up by adding 4.1 or 4.56 gears in the back and not changing the gears up front? Also, I think I'm gonna go w/35" tires. Do you guys recommend the 4.1 or the 4.56 gears? I think I'll eventually move up to 37s, so I'm thinking 4.56s. I still have some research to do to really understand the differences between the 2, but can you offer some goods/bads for each? Thanks very much.

You will be better off with the 4.56's if you are going to go 37's.

As for running different gears front and rear. It won't hurt anything as long as you never shift into 4wd. Having the front and rear wheels turning at different ratios is a quick way to find your weak link in the drivetrain!

:withstupid: :withstupid: Deffinately go with 4:56's for 35 or 37 inch tires. Also as stated you can run different ratio as long as you dont put it in 4wd. If you I would remove the front driveshaft until you get the front gears installed. That way you can still put the transfer case in 4lo and have 2lo.
