If any of you with bigger tires are even thinking about changing ring and pinion...

DO IT.

Before I put my lift on my H2, my gas mileage was roughly 11-12 mpg. That was driving mostly city, minor highway.

When I put the lift with the 38's on it, my mileage immediately went from the 11-12 mpg to 8.6-9.1 mpg.

My logic was to install 4.56's which would bring the truck as close as possible to the stock configuration.

Point is, though I only installed them this weekend, I am averaging 11.0-11.5 mpg with way more power.

Excluding the labor because I did it, I've got less than 700 bucks in it. At a 2-3mpg increase, it won't take long to cover the cost of the gears.

Anyway, DEFINITE improvement, well worth the effort and money.
