Re: What is your mpg with lift?
I'm running MT 39s with a 6 inch lift. I have the speedometer with black tape marks on it, when I calibrated it running along side of my son's Impala and he phoned me the speeds. Using this info and guestimating, I would say in the low 10s or high 9 mpgs.

Haha. If I get what some of these guys are getting when I get a lift I'll be one happy camper. And true, we didn't buy it to complain about the gas, I was just curious on everyone's number with the lift.

Re: What is your mpg with lift?
I have Rancho lift with torson keys and 1 1/2" rear coil spring spacers, 40" Mickey Thompson Baja Claws tires, Magnacharger, 4.56 gears and I am getting around 8 MPG in city and 10 on Hwy.

Re: What is your mpg with lift?
6? lift, 37?s with 4.56 gears...
20-22 hwy
18-19 city
Ohhhh, before the diesel conversion...lol. I could hit 9.5-10 (with supercharger) on average.
You will lose about 2-4 mpg putting bigger tires on it. If you install 4.56 gears (which I strongly suggest) you will get 2-3 mpg of that back.
HTH?s,
Mark
