I have a 2002 silverado z71 that I want to lift. I am debating between a rancho 4" suspension lift with 33" tires and a pro comp 6" suspension lift with 35" tires. I really think the 6" with 35s will look awesome but since this is my daily driver I don't want to kill the gas mileage too much. I will be installing dual exhaust, air intake and a performance chip also in order to get performance and mpg back to normal as much as possible but I don't know how much it will help. I also have 4.10 gear ratio from factory so that would be OK with 35s. I am getting 14+mpg city right now and wouldn't want it sub 12mpg if possible. If anyone has experience with this please let me know.
This is my first post ever on a forum so if I break any protocol be easy on me
