is it an sas truck? do you have a 3 in body lift?
its a good torque intake for a 4x4.
the car intake is easier to use, but you will have to modify your truck harness to work with the car intake(or just get a car intake/pcm) as the throttle body ect are located in a different location, and will want car fuel rails as well if you are using the truck harness and rails.
a straight axle truck will allow a x member that can let the engine down a bit more so that truck system will fit nicely.
