Zippers Red Shift Cams RS587 for '99-17 Harley Davidson Twin Cam Models (Select Year Range)
This cam was designed and optimized to be the best bolt-in cam for the Harley-Davidson® CVO® engines. The RS587 cam dramatically increases power and torque across the entire RPM range. Unlike other cams, the RS587 was designed to work with the larger valves and heavier springs that the CVO engines are equipped with. The RS587’s specially designed cam lobe ramps ensure quiet operation of these heavier parts, while the lobe profiles take advantage of the high flow CVO heads to develop more power to red line.
The RS587 was specifically designed for VALVE TRAIN components AND LOW COMPRESSION in the CVO 103 AND 110 engines. No compromises were taken in this design to optimize these cams as the best bolt in design.
The RS587 revs freely and pulls to nearly 6,000 rpm for a true hot-rod feel. The difference is simply amazing for a bolt-in cam. This setup will produce approximately 200psi cranking compression in an unmodified CVO engine.
Although Zipper’s offers higher output options for the CVO® engine, the Red Shift RS587 is the best option for a bolt in cam with performance exhaust and EFI tuning without increasing compression or opening up the top end.
