Lift & Factory Rake Question
What is the purpose of the factory rake on these trucks? I know it probably helps a bit with a load in the back so that it is not sagging, but how about for aerodynamic purposes? Does it play a role in that?
The reason I ask is because when looking at lifts there are (as we know) a lot of choices and some are for example 2" front leveling kits and 2" susp lift kits. The latter will keep the factory rake while the former eliminates it.
By installing a leveling kit, will that hurt the truck's aerodynamics and therefore hurt fuel mileage?
Also, will installing a 2" susp lift kit hurt fuel mileage compared to my stock setup? If so, how much would you say?
