For ultimate utility, the package includes a remote-mounted quick connect, a high-pressure tire inflator hose with a dedicated storage bag, a 160 PSI panel-mounted gauge for effortless monitoring from inside the cab, and a locking air chuck equipped with an integrated digital pressure gauge and pressure release valve. System comes complete with all necessary air lines, wiring, and high-grade hardware. Built to endure the toughest environments, this complete package provides the ideal balance of discreet original equipment manufacturer style mounting and high-output pneumatic performance that serious truck builds count on.

Special Note for Dodge Ram (Classic/DT/DS)

Since Dodge/Ram manufacturered concurrent Ram 1500, 2500 & 3500 models on both new and old body designs, please ensure you select the parts to suit the correct submodel. The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.
