We have made sure that the receiver air shocker will fit into most Ford, Chevy, Dodge and SUV’s. There are some clearance issues with the Chevy Envoy, Ford Explorer, some imports and service body vehicles where the body extends below the receiver tube. The use of “reducer” sleeves on trucks with a 2 1/2″ receiver tube is not recommended. The Shockerhitch is available with a 2 1/2″ shank at no extra charge. Please indicated which vehicle you intend to use the hitch with, make/model/year and we will attempt to get you a great fitting hitch.
