Reyco Granning’s R-Series suspension is the fast, easy way to upfit your chassis cab Dodge truck with an option the factory doesn’t offer: the matchless comfort, handling, and safety of air ride. The wear pads react lateral loads from the tires into the frame. We designed it this way to improve packaging, allowing us to eliminate the traditional transverse rod mounted between the axle and frame.

This arrangement allows OEM’s to package frame cross members, fuel tanks or exhaust between the frame rails. This eliminates the need to weld an expensive transverse rod bracket on top of the axle. In a deep kneeling scenario required for ambulance applications and others this transverse rod bracket can intrude into the body when the air is exhausted. Field-proven for 20+ years, the R-Series conversion kits are complete air systems custom designed for the Dodge chassis cab. The fit is precise and the bolt-on kit installs in half the time –– no welding or costly modifications needed.
