[QUOTE="true98jeep, post: 983654, member: 8556"] Strokin best I can say is start playing with the gear calculators. There are calculators where you can put in tire size axle ratio and then transmission ratio. I did that to figure up my rpms on a stock factory truck and then played with it to get gears that matched it almost perfectly with the 37's. With 40's I would be looking to start in the 4.88 or maybe even 5.13 range. and see what figures those toss you. [/QUOTE]
