4.56s are in.

[The big beast!]

Thats an awesome deal to have that work done for 100-200 bucks? The best price I've gotten for front and rear is 600, 900 is pretty high though.

well that was 900 with a cheap set of gears!

Just crank and 315/75 16s

Wow and it's not rubbing? I'm running that size tire with 10" of lift and I still had to trim the front plastic! If you can run them with no lift I think i should be ok with 37s for my next set of tires.

oh ok that sounds a little better, but you should be able to get some decent gears from 4wheelparts.com or performance4trucks.com, I had g2 4.56 gears front and rear and an rear end rebuild kit for about 350 bucks.

That sounds pretty cheap! I think I'll just read up and do some research and regear it myself.

i took the front plastic off and it only rubs on the a-arm at full lock.

 

[k_pro1992]

well it looks like im going to have to regear the front myself, will it hurt anything if i use a different brand of gears in the front of the same ratio or do i have to use yukons for the front too?

37's are hard to run on 6" lift. You have to be FULLY cranked, and it is hell on the suspension.

Will the 4.56's help with mpg?

 

[90chevstepside]

With stock tires? No way. Your gas mileage will go down, and your top speed will be drastically lower.



With large tires 35-37's, they will return the drivetrain to close to "stock". Your gas mileage will be better with 4.56 and 37's than it will with 3.42's and 37's. Trust me, it's a huge difference.

But it won't make it better than it already is.
