- Can be used with stock valve springs
The S&S Cycle 99-06 BT 509C Chain Drive Camshaft Kit is engineered to deliver high torque performance for Harley-Davidson Dyna models from 1999 through 2006, excluding the 2006 HD Dyna. Designed as a bolt-in upgrade, this kit enhances engine power without requiring extensive modifications. With a cranking compression of 180 psi, it eliminates the need for compression releases, making installation straightforward for engines with a stock compression ratio. This camshaft is ideal for 88 CID engines and supports idle speeds from 4500 rpm, providing a balance of performance and drivability.
Built to be compatible with stock valve springs, the S&S 551 cams are a popular choice among late-model bagger riders. However, due to its .550-inch lift, the 551 cam cannot be installed in early Twin Cam 88 engines (1999-2004) without upgrading to high-lift valve springs, which involves removing the heads. This kit simplifies the upgrade process by offering a direct bolt-in solution, saving time and reducing costs associated with head removal.
Designed specifically for Harley-Davidson Dyna models, this camshaft kit fits a wide range of bikes including the FXDX Dyna Super Glide Sport from 1999 to 2004, FXDXT Dyna Super Glide T-Sport, and FXSTDSE Screamin Eagle Softail Deuce from 2003. It is a reliable choice for riders seeking to improve engine performance while maintaining factory valve spring compatibility. The kit's straightforward installation process makes it an excellent upgrade for both professional mechanics and DIY enthusiasts looking to enhance their Harley-Davidson's power and responsiveness.
Constructed with precision and durability in mind, the S&S Cycle 99-06 BT 509C Chain Drive Camshaft Kit ensures long-lasting performance in demanding riding conditions. Whether you're upgrading for better acceleration or improved throttle response, this camshaft kit provides a significant boost in engine output and overall bike performance, making it a valued addition to your Harley-Davidson maintenance or customization plan.
