It wouldn't change your ride in the rear at all.
This is what most members do. The odd ones also grab 5100's for the rear but I would say 8/10 do just the fronts, but it is ultimately your call.
Let me know if you need anything further of if you'd like to grab them
Dont have 25 posts yet...but
thanks for such a quick response to my thread! Wow thats a great deal for the two front bilstiens...but would that effect the way it rides in the rear of the truck? and I was wondering if I would need to do anything to the rear of the truck?
