Help, I'm in biloxi Mississippi and about to move from 35 to 37 inch tires. What I need is some advice on gears and a shop to install gears.
4.56 or ?.?? Higher?
And does anyone know of a shop in the biloxi, southern mississippi area that can install them without the dreaded gear whine?

 

4.56 would work just fine imo.

 

A 4.88 is much more suitable for a 37" tire. A 35" tire is best suited with a 4.56 ratio.

 

agreed, I have 4.10s and 35s and it has more than enough power.

 

4.56 if you cruise highway a lot. 4.88 if you offroad or tow a lot.
