Hi, I just added 35's to my truck and its going in and out of overdrive alot and is a pain in the ***...lol i have the factory 3.73 gears and was wondering if I should go to a 4.10, or 4.56 gear?

sorry, im used to jeeps, just got rid of my 08 rubicon on 42's with 5.13 gears

 

4.56's.

4.10's barely get you back to stock effective ratio (and are not big enough jump from 3.73's to be worth it) - you need to compensate fer the significant additional rotational inertia.

Plus - the 4R75E has horrible ratios to begin with - especially 1st.

 

ok, thanks 4.56 it is. thinking about adding an electric locker while its apart too

 

next question, i know i have the 9.75 3.73 lsd rear end, but what is the front? i know its ifs and not solid axle..lol but what do i search for when looking for gears

 

IF I remember correctly when I had mine regeared it is the 8.8 frontend(I would have to go back and look it up to be absolutely certain). And I second the 4.56's and 35" tire combo, best thing I have ever done to my truck.

 

Thats for sure. First is very high.

 

yeah, i found them on ronsmachiningservice.net for $650shipped for the complete kit
