Re: 2003 H2 with 12" lift and 42s
She had 38 or 40s on the previous 6" fabtech running stock gears. Thats so far off some the stock ratio, its horrible gas mileage. Even going up another size, I can see getting an improvement w regearing- gets you back in that "power band".
I went from 12 to 8.5 w/ my wheels/tires, im almost finished installing 5.13 gears in my ride. I'm thinking I should be back around 9.5-10mpg.
