For a coupler lip width of 5 inches your best option would be to look into a wheel lock since none of the coupler locks we offer will fit around that wide of a coupler. For a wheel lock we have the Stallion Wheel Lock part # 288-02020 which would be a great option. Then for a lug nut lock set we have the part # RG01-150. view full answer...
