What is the main benefit of using a gear drive camshaft over a stock chain drive?

The primary benefit is improved valve timing accuracy. Gear drive systems eliminate the timing chain and its tensioner shoes, which can wear out and introduce slack. This results in more precise timing and removes a potential failure point.

Does this camshaft kit require upgraded valve springs?

No, this 475G camshaft kit is designed to work with your motorcycle's stock valve springs. This simplifies the installation process and can help keep costs down.

What specific Harley-Davidson models does this camshaft kit fit?

This kit fits 1999-2006 Harley-Davidson Big Twin models, excluding the Dyna line. Examples include the Road King, Heritage Softail Classic, Fat Boy, and Road Glide. It's always best to consult the detailed fitment list for your exact model and year.

Product Details

S&S Cycle is well-known for building performance engine components for Harley-Davidson motorcycles. This 475G gear drive camshaft kit is designed as a direct bolt-in replacement for 1999-2006 Harley-Davidson Big Twin models, excluding the Dyna line. It's a great option if you're looking to remove the factory timing chain system without necessarily chasing more horsepower.

By switching to a gear drive system, you eliminate the timing chain and its associated tensioner shoes, which can wear out over time. This means more accurate valve timing and one less component to worry about failing. The 475G cam offers a .475 inch lift on both the intake and exhaust, with a duration of 216º at 0.053 for the intake and 220º for the exhaust. This cam profile is designed to work with your stock valve springs, making installation more straightforward.

This kit includes the 475G camshaft and the necessary inner gears to complete the conversion. It fits a wide range of Harley-Davidson models including the Road King, Heritage Softail Classic, and Fat Boy. Refer to the manufacturer's installation instructions for specific details on the conversion process.
