i think 4.88 are a tad low. since its 2wd and not a mudder keep the better gas milage. go 4:56 i had 4:88 on 44's and i could burn em and 5:38 on 49's and could burn em. i think 4.88 with 37 are overkill.
just my .02

 

YOU DONT GET GEARS FOR BETTER MPG, YOU GET THEM TO TAKE THE STRESS THAT THE BIG TIRES PUT ON YOUR TRANSMISSION. TRUST ME THEY WILL PAY FOR THEM SELVES BY KEEPING THAT TRANSMISSION GOING STRONG. DONT HAL******* A BUILD GET YOUR RING AND PINION CHANGED ITS NOT THAT EXPENSIVE ON A 2WD.

If you think 4.88's are too low then go to a 4.30 or a 4.56

i believe they make a 4.30 for the 9.75. I know for a fact they make 4.56's though.

 

You figure you gear ratio then, current tire size divided by stock tire size times your current gear ratio and thats what you need in order to make it run like stock again. like for me it would be 35/32*3.73=4.079 so i would run 4.11s to get it back to stock cause thats all ya need if your running 30 miles a day.
