What's your current ratio?? 4.10 is fine for 33's. 4:56 would be a good bet so you can go bigger in the future and not have regear for 35's.
If you are 3.73 now, since you are 2wd, I'd suggest finding a junkyard 8.8 w/ 4.10 gears....probably around the $200 range....ALOT cheaper than the install on the new gears.
I thought there was a nice chart somewhere that shows tire size, revolutions of that tire per mile, and gear ratio....i can't seem to find it.
YOU WON'T GAIN HORSEPOWER OR TORQUE!!! What you will gain with a lower gear, is more toque in a lower engine rpm range......at the cost of higher rpms at higher speed....so you'll lose some top end. Meaning, it'll be faster off the line, w/ a lower top speed. Guys...confirm that for me.....i don't think it came out right. lol.
