What valve springs are needed for this camshaft kit?

For 2005-2006 model years, you can often reuse the stock valve springs. However, for 1999-2004 models, special high-lift valve springs are required to accommodate the camshaft's increased lift.

Are pushrods included with this kit?

Pushrods are not included with this camshaft kit. Due to the high lift of the 585C camshaft, S&S Cycle recommends using their adjustable pushrods for proper installation and optimal performance.

What other modifications are recommended for best performance?

To get the most out of this performance camshaft installation, it is recommended to also install a high-flow intake system and a high-flow exhaust system. This ensures the engine can breathe effectively with the improved camshaft.

Product Details

With an intake valve lift of 0.585 inches and exhaust valve lift of 0.585 inches, this S&S Cycle 585C camshaft is built to significantly improve your engine's performance. It's designed to deliver noticeable gains in both horsepower and torque, particularly in the 1500 to 5000 rpm range, which is where you'll feel it most during everyday riding. This kit is a popular choice for owners of 1999-2006 Harley-Davidson Big Twin models, including popular lines like the Softail and Dyna, offering a substantial performance upgrade without needing extensive modifications.

This camshaft kit is well-built and optimized to take advantage of the extra airflow from ported stock heads or S&S Super Stock heads. Because of its high lift, it's recommended to use S&S adjustable pushrods for proper installation and function. For 2005-2006 model years, stock valve springs can often be reused, but for 1999-2004 models, special high-lift valve springs are required to handle the increased cam lift. To truly unlock the full potential of this performance cam, pairing it with a high-flow intake and exhaust system is also advised.
