Default What gears to use with a hemi?
I just got done with my 5.7 hemi and was wondering which gears work the best with 35's and 37's?

4.88's have been working nicely for us, both on and off-road.

I have 5.13's on mine and think it's great...but have nothing to compare it to. I think you could probably leave the 4.10's on with the 5.7L because it has enough torque to get the Jeep going no matter what.

If you are climbing mountain passes or towing, you may want the lower gears, 5.13, or 5.38.

I have 5.13's with my 6.1 and they work great. I am running 37s for now but plan to go up to 40s that is why I choose the 5.13's.

i am running 6.1, stick and 4.88 with 38" tires and it works just great for me. as some have mentioned above, with a hemi i do think even 4.10 and 35 would just do fine.

We have done a bunch 5.13 and a few 4.10 and even 3.73 it really just depends on how you are going to drive it.

Default Gears
14 is not too bad, I guess I'm leaning towards 5.13's.
