4.56 and should be good..

 

You'll need that tune immediately after the gear swap. Just so you know.

With 33" tires it will probably turn the same rpms as factory size tires with 3.73 gears.
There's a calculator that will tell what you'll turn with gear/tire size.

 

thanks! do you know where i could get them from for a good price?

 

Rons machine shop has good deals. Get yourself a package deal with a good posi unit.

 

I really feel sorry for that little 4.8

 

cool thanks!

 

I know!! hah thats why i need those gears and a posi unit soon!!! also upgrade my tranny cuz i feel its not gonna last long

 

I ran 33x12.50s and 4.56s and it felt perfect. I destroyed a set of USA standards in about 3 months though.

 

Forsure Im going to get 4.56! How long did they last you cuz those are the gears that come in the gear posi package that I want to get
