About This Product
Zodiac rocker box housing screws replace OEM 3997A. They fit Evolution Big Twin and Sportster engines. They match the original equipment style. They seal the top end properly. You need them for routine maintenance or a full rebuild when you pull the rocker covers. Each screw is sold individually. The finish withstands the heat and vibration of an air-cooled V-twin.
