So whats better. to put the rear top shock mounts on the cross member in the center of the truck or mount the shocks in the factory location. Mime are in the factory location now and only about 4 inches of the shock is extented . I don't think this is enough. So i'm going to cut the factory ones off and build extentions. so should i build the mounts in the center of the truck or build them on the frame rails
