Sealing kits for the primary drive

Whether lubricated with spray oil or running in an oil bath, primary drive housings from 4-speed models upwards need seals: Knucklehead and Panhead with sheet metal primary, Shovelhead, Evo, Twin Cam and Sportster with aluminum primary. A complete gasket set is always worthwhile.

Complete gasket sets are a tried and tested way of making sure you have all the gaskets you need and don't forget anything. A gasket set in the garage is also a smart way of stockpiling. If something needs to be repaired quickly, the required gasket - e.g. a cylinder head gasket - is already there and does not have to be ordered first. Just don't forget to reorder the individual gasket after the successful repair.

Our gasket sets are made by James and contain all the gaskets needed to reseal a primary.
