      Cast Aluminum Spinner Gas / Oil Cap With Weld-In Steel Bung

      Well made! Just fresh up the threads after welding so you don't seize up the alu threads in the cap:)

      Lowbrow comes thru with quick turnaround

      Great to have the gas cap in a quick turnaround from online ordering. Perfect vented replacement for the one that was lost in the middle of the night on the road.
