I'd like to here from any 3500's with 6.7, Aisin transmission, and 37 inch tires on what ring and pinion set they went with and why. The reason I ask is I'm getting 37's mounted today and a Carli suspension installed next week. I don't plan on keeping the stock gearing, but I will be driving it home on stock gears. I've seen a few different setups in a few forums ranging from stock gears, 4.10, 4.30, and 4.56.
The shop I've talked to was very specific in telling me their opinion based on the gear calculator they use, my stock setup, and what tires I want to go to.
They said if I was going to be doing any large toy haulers, based on their gear calculations and 4th gear, I should re-gear with 4.10.
I don't have a toy hauler yet, but I want to gear accordingly, and I only want to do it once.
