Product Description This completely Billet Kit will suit any Airhead with an Original Tank, it comes with a beautiful Genuine Aluminium Monza Cap (2 1/2″) as standard (not the cheaper Chrome ones!),  with a matching screw-on threaded Ring and of course the Conversion neck itself that proudly bares the VonZeti name engraved on it’s inner collar, so you will think of us at every fuel stop. What’s not to love?! This Kit will simply screw in place of the original Cap, we would however recommend using a Loctite type solution to secure the cap in place and for security.
