🔥 Performance Benefits:
10° Exhaust Duration Boost (Cylinder 2): The 10° increase in exhaust duration on Cylinder 2 results in better exhaust scavenging and flow, leading to enhanced power delivery and smoother acceleration. This modification is the key difference that makes the 264 Rebel camshaft superior to the S&S 475, especially for V-Twin engines.
Mid-Range Torque & Top-End Power: The 264 Rebel camshaft is designed to boost mid-range torque while delivering additional power in the top RPM range. Expect faster throttle response and quicker acceleration that outperforms the S&S 475 cam, especially under load.
Improved Exhaust Flow: The added exhaust duration modification improves exhaust scavenging in Cylinder 2, maximizing the engine’s efficiency and enabling higher horsepower throughout the powerband.
Smoother Idle, Stronger Performance: With a slightly lumpy idle and increased power, this cam provides the signature Harley V-Twin sound with improved drivability—perfect for both street and light racing use.
Better Than the S&S 475: While the S&S 475 is a solid cam, the 264 Rebel camshaft offers better exhaust timing and a more aggressive powerband. It's a step up in performance for anyone looking for a real performance cam that maximizes the Harley experience.
🧰 Installation Notes:
Spring Requirements: Depending on your bike’s setup, you may need to upgrade to performance valve springs to handle the increased lift.
Timing and Tuning: It's highly recommended to degree the cam and tune your bike after installation to achieve the best results. The 264 Rebel cam requires precise timing to extract the full potential from the exhaust duration enhancement.
Exhaust System: Pair this cam with a high-flow exhaust system to complement the increased exhaust scavenging and maximize performance. Consider using performance headers or custom exhaust setups to get the most out of the cam’s design.
Lubrication: Be sure to use ZDDP-rich oil during the break-in period to prevent premature wear on the cam and lifters.
