Anyone care to share their thoughts and/or experience concerning the benefits of a lift, bigger tires, and the impact to MPG?
I'm considering getting a 3 inch lift for my 2008 GMC Savana with the 6.0 liter gas engine, Quigley 4x4, 4 spd transmission with tow mode, and 4.10 gear ratio. Lift would be Weldtec Designs. According to Jeremy, the lift with their rear spring will provide a much better ride. Of course if I want to go much bigger than the stock tire height, a lift or trimming would be required.
I'm sure the answer to the MPG question depends on many factors, I'm trying to get a range of possible impact. Tires may have a bigger impact than lift. Of course weight, vehicle size, engine, transmission, gearing, etc. all play a part as well.
I've done some searching but haven't found anything specific to this for vans. Fair amount of previous talk around this, but not specific. My google-foo/search-foo may not be good enough either so if I need to be enlightened, go right ahead.
