Hello Peter, thanks for reaching out. Since you have 5,200 lb axles the correct Roadmaster comfort ride system will be part # RM49NQ. This is for 6K axles but those will have the same 3" diameter a 5.2K axles so this will be the kit for you. This comes with the slipper spring upgrade and the shock kit.
