Zippers Performance Red Shift Chain Drive Cams Harley Twin Cam 07-17

Red Shift® Chain Drive Cams by Zipper’s Performance are engineered to transform your Twin Cam® engine into a high-performance machine. Whether you are seeking immediate low-end passing power for a heavy touring bike or looking to unlock the hidden potential of a CVO platform, these cams provide a significant increase in power and torque across the entire RPM range without compromising reliability.

Designed as high-output "bolt-in" options, these camshafts are optimized for modern engine dynamics. High-Torque profiles create an extremely fast and turbulent inlet charge in the combustion chamber at low RPMs, inducing the turbulence necessary for immediate throttle response and acceleration. This makes them the perfect choice for riders dealing with mountains, passengers, or heavy trikes—allowing you to stay in 6th gear and simply turn the throttle when you need power.

For high-displacement applications, specialized profiles take advantage of larger valves and high-flow heads to ensure the horsepower curve pulls freely to redline. Unique cam lobe ramps ensure quiet operation of heavy-duty valvetrain components, resulting in a textbook-smooth torque curve that never loses momentum. These designs offer a true "hot-rod" feel, allowing your engine to breathe and rev freely far beyond factory limitations.

Technical Notes and Recommendations:

• Application: Fits 2007-2017 Twin Cam engines (also compatible with 2006 FXD models).
• Installation: Designed as bolt-in components that can be used with stock or adjustable pushrods.
• Maintenance: We recommend installing new cam bearings and performance tappets with any cam change. For maximum throttle response and reduced valve train noise, use with Red Shift® Dual Piston Cam Chain Tensioners.
• Performance: Optimized to avoid engine-damaging detonation while maximizing output for today's fuel quality.
