Lowbrow Customs dished gas caps are precision-machined out of solid aluminum and paired with an injection molded base and gasket that fit 1996 & later Harley-Davidson motorcycles as well as most aftermarket gas tanks. These gas caps are slightly smaller diameter than a stock cap for that custom look and feature a knurled band for easy tightening and removal, with or without your gloves on. 2-1/2 inch diameter, vented. Made in the USA.
