Thanks guys!! It's a Bell Tech 5/7 with Air Lift Slam Air bags. Did front end rebuild, brakes etc... also. I drive it frequently but not my daily. The dually's main job is to pull our 28' Haulmark Edge race trailer. I've been meaning to do a build thread here ever since I bought it but never have. Guess I should actually do that. I do have a build thread on GMT400.
