Chrome-plated aluminum screw-in caps with a low-profile design that measures only 3/8"-tall. The exclusive ratcheting feature provides proper torque. The vented gas caps have right-hand threads, and the non-vented caps have left-hand threads. A dummy gas cap is available to replace the fuel gauge gas caps found on some late model Big Twins. Sold each.
