Gas milage to be expected with a 3" lift

[Agent_51]

Ok so right now i have an almost stock 2000 4dr SOHC that im wanting very badly to put the pro comp spindles on.

The only mod i have done so far is an cat back bullet exhaust system with single out, though a KKM or K&N is for sure in the works.

I crawled under my X and found that i have 3.55 gears.

So with that information in mind, maybe someone here can give me a good estimate, or factual information if someone has the same setup, as to what kind of gas mileage i would get with that procomp lift and 31s.

And if a regear would help, what would be the best ratio? 3.73? 4.10?

Thanks guys.

Just going to 31"s, there isn't an absolute need to change gears. Though you'd want to go 4.10 since 3.73 won't do much at all. Without the gear change, you're mileage will pretty much stay the same. Hwy mileage might go down 1-2 mpg with 4.10s.
