About This Product

S&S billet oil pump kit fits Big Twin engines from 1970 through 1991. It replaces the original cast pump with a billet aluminium body that resists warping and wear. The tighter machining keeps oil flow and pressure steady to the top end and bottom end. It works on stock or modified motors. S&S builds it as a trusted choice for both. Sold as a kit.

Manufacturer part number: 31-6203.
