Lowbrow Customs dished gas caps are precision-machined out of solid brass 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. These are solid brass, not brass plated, as you will know when you hold it in your hand! 2-1/2 inch diameter, vented. Made in the USA.
