S&S CYCLE Cam with Plate - 551 Series 310-0815

Stock cam timing and lift limitations leave power on the table—the S&S 551 Series addresses this with higher valve lift and optimized cam events that unlock additional horsepower across the powerband. This bolt-in upgrade replaces critical engine internals with purpose-built S&S components, eliminating weak points like factory cam chain tensioners and delivering the reliability demanded by serious riders. Whether you choose gear-drive or chain-drive configuration, you're investing in U.S.-manufactured precision engineering that transforms engine breathing and performance.
