I'm running 35" tires and thinking of installing 4.10 gears. If I swap the gears, would I gain a few mpg since the 4.10 will put it back in its powerband?

 

You won`t gain a FEW mpg. , maybe a half mpg. if you`re lucky. You still have the larger heavier rotating mass robbing mpg.

Don`t spend the $$$ on a gear swap , and ever expect to recoupe your money in extra fuel mileage.

 

But your tranny or clutch will like it.

 

Thanks.

 

I still get pretty good millage with my tires 21-22 highway. Not worth a gear change in my opinion.
