What is the advantage of a gear drive camshaft over a chain drive?

A gear drive camshaft eliminates the timing chain and its associated components, which can develop slack or lash over time. This gear-to-gear setup ensures more precise valve timing, leading to improved engine performance and reliability.

Do I need to replace my starter when installing this camshaft?

No, the 'Easy Start' design of this camshaft is specifically made to work with your stock starter. It allows the stock starter to handle the increased load of starting the engine, even with the performance enhancements from the cam.

What specific installation considerations are there for different model years?

For 1999-2004 Harley-Davidson big twin models, these cams are not a direct bolt-in and require special springs. For 2005-2006 models, they are a bolt-in installation and can use the stock springs.

Product Details

Starting with the gear drive design, this S&S Cycle 570GE camshaft kit is built to significantly improve valve timing accuracy. By eliminating the timing chain lash that can occur in stock setups, you get a more precise and consistent engine operation. This is a substantial upgrade for Harley-Davidson big twin models from 1999 to 2006, excluding the 2006 HD Dyna models which require a different cam style.

The 'Easy Start' feature is a notable benefit here, as it allows your stock starter to handle the increased load of starting the engine, even with the improved performance this cam offers. The .570 inch lift is designed for 88 to 96 cubic inch engines that are running a compression ratio between 9:1 and 10:1, making it a solid choice for those looking to enhance their engine's breathing and powerband. For 1999-2004 models, be aware that these cams are not a direct bolt-in and will require special springs. However, for 2005-2006 models, they are a bolt-in installation and can utilize stock springs.

This complete kit comes with the cams featuring their integrated inner gears, along with all the necessary installation hardware. This comprehensive package means you have what you need to get the job done and experience the improved performance and reliability that S&S Cycle is known for. It's a well-built component designed to make a real difference in how your engine performs and starts.
