S&S Cycle 78-84 BT 560S Camshaft

This is the S&S Cycle 560S camshaft, designed for 1978-1984 Harley-Davidson Big Twin models. It's built to give you a noticeable boost in power across a wide range of your engine's operation, specifically targeting the 3,500 to 6,000 RPM band. This cam is a solid choice if your engine is between 88 and 103 cubic inches and has a compression ratio between 9:1 and 10:1, as it's engineered to perform best in those conditions.

You'll find this camshaft offers excellent power delivery throughout the RPM range, making it a popular upgrade for riders looking for improved performance. It's important to note that this cam is not recommended for stock displacement or lower compression engines, as it's designed for engines with a bit more breathing room. For 1980-1981 engines, you'll need to convert to late-style valve guides. You'll also need high-lift valve springs and should perform normal clearance checks during installation. Using solid lifters or aftermarket hydraulic tappets is also recommended to get the most out of this camshaft.
