If anyone in the Northern California area is interested in making a change to 3.73 gears let me know. I am looking for 4.10 gears. My truck is a 06 with 40K miles, never abuse.

Or if you know of gear vendors with good prices, please advice.
Thanks

Curious as to why you are wanting to go to the 4.10's.

Cool...At one time I was thinkin about droppin from my 4.10s to the 3.73's for better fuel mileage, but think I am just gonna keep mine and save up for the over/under gears from gear vendors. Best of luck to you.

i have 4 tens on my truck and went with 35's no it feels like i got 3 73, anyhow i had a machinist buddy of mine do some math and he told me that my new effective gear ratio was 3 63 even though they were 4 10 with the big tires. what do yall think? i know i hate that it has some lost low end power and i do have to keep my foot in it more now....

yes, raising your tires size does effectively make your overall gear ratio smaller. not only are bigger tires heavier and harder to turn, but the cut down on the amount of force you are putting to the ground (torque being force X distance: constant torque going through a larger lever arm, ie: bigger tire, lessens the actual force on the road) you combat this by getting steeper gears. the tire and road act just like a rack and pinion so a bigger tire works like a shallower gear ratio

by the way its 4.10 not 4:10 short for 4.10:1. 4:10 would be a 2.5:1 and would be pretty high gearing

just a pet peeve of mine and thought i would pass on the info
