What about a gear swap?

Will 4.10 gears be better than the 3.73? Will i have more pulling power? How much would a swap cost me? What will the mileage do with the change?

I actually think in town a 4.10 gear DOES give better mileage. On the highway though they rev up to 2200 at about 75ish. Not where you want to be for the best MPG. I also think the 4.10s will do better, mileage wise, with the larger tires (35") than a 3.73 geared truck. There is more torque available to the wheels so its not lugging the engine as much.

I have 4:10 gears and my rpm is at 2100 going 80mph with 35" tires..... when you have bigger tires put in it will effectively reduce your gearing. I get 18-20 on the highway depending on wind direction and 16 in town....I only have a leveling kit on it though. procomp xtreme all terrains 35x12.5......

How much would it cost me to change the gearing from 3.73 to 4.10?

Argo

couple of grand for front and rear......

zack birge

Get a good tranny in there and don't worry about the gears for now. I run on 35's and tow a 14k toy hauler without issues with mine.

Stock tranny was a whole nother issue though. It would rev to like 2800 rpms leaving a stop light, and like 3k trying to go up a hill if I had to stop at the bottom. It was horrible. Transmission took care of that though.
