What components are included in this S&S Cycle camshaft kit?

This kit includes the MR103G gear drive camshaft. While it is designed to work with stock valve springs on 2005-2006 models, other components like oil pumps or cam support plates are recommended but not included in this specific kit.

What are the recommended upgrades when installing this camshaft?

For optimal performance and reliability, S&S Cycle highly recommends upgrading to an S&S oil pump and cam support plate. Additionally, a 2007 and later style hydraulic cam chain tensioner upgrade is advised, particularly for chain drive applications.

Can this camshaft be used in California?

No, this camshaft is not CARB approved and therefore cannot be shipped to California due to emissions regulations.

Product Details

This S&S Cycle MR103G gear drive camshaft kit includes the camshaft itself, designed to fit a wide range of Harley-Davidson Big Twin models from 1999 through 2006, excluding the 2006 Dyna models. If you're looking to get more out of a modified engine, especially one with larger displacement and higher compression, this kit is built to deliver a notable increase in torque and horsepower beyond what typical bolt-in cams can achieve.

The MR103G camshaft features specific timing and lift figures: intake opens at 13º and closes at 33º, while exhaust opens at 50º and closes at 22º. At 0.053 lift, the duration is 226º for the intake and 252º for the exhaust. Both intake and exhaust valves achieve a lift of 0.585 inches, with lift at Top Dead Center measuring 0.172 inches for intake and 0.177 inches for exhaust. While stock valve springs from 2005-2006 engines can be used with this cam, S&S Cycle highly recommends an S&S oil pump and cam support plate, along with a 2007-and-later style hydraulic cam chain tensioner upgrade, especially if you are using a chain drive setup. For maximum performance gains, pairing this camshaft with performance intake and exhaust systems is advised.

This kit is a solid option for riders aiming to enhance their engine's performance. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding your build.
