About S&S Cycle Billet Tappet Covers For Twin Cams
S&S Cycle Billet Tappet Covers For Twin Cams
- CNC machined from billet aluminum and polished to a show finish
- The CNC machining assures accuracy, while the billet material provides extra strength and dimensional stability over a wide temperature range
- The nature of billet aluminum makes it a perfect choice for an application such as this where oil leaks cannot be tolerated
- Unlike cast aluminum, billet has none of the internal voids or impurities which are inherent in a casting
- Billet is not subject to residual internal stresses caused by thermal contraction of the metal as a casting cools
- Fits stock and S&S Twin Cam style crankcases.
