Radius breather bolts from Lowbrow Customs feature an innovative design with 5-ply sintered stainless steel mesh, providing the proper breathability for your motor while keeping a slim profile and a completely custom look. An internally broached allen allows for a quick and hidden installation method, with the stainless breather element and circlip finishing the job. A perfect match with your choice of air cleaner and carburetor support bracket, these 3/8″-16 thread breathers fit 1999 & up Harley-Davidson Twin Cam motors. Available in chrome plated steel, black electroplated steel, or brass. Made in Ohio, USA.

NOTE: The threaded section of the breather bolt measures approximately 11/16″ long, measure the aftermarket air cleaner thickness to make sure it will work with your application.
