Red Shift Cams® 509S for Shovelhead®

Red Shift Cams® Performance Cams for Evolution® Big Twin Engines
For over 3 decades, Red Shift Cams® have been the choice of high performance engine builders for aftermarket H-D® applications. Master engine developer and Red Shift Cams® camshaft designer Dick Hilferty has always been at the forefront of the most advanced designs in all forms of racing and performance applications. Today Dick’s designs are manufactured at Zipper’s with the most advanced engineering design processes built into every cam. Red Shift Cams® will provide you with the most advanced components for power gains and unrivaled valve train dynamics. Maintaining valve train control should be every engine builder’s first concern when choosing a camshaft. A lack of valve train control, or noise, simply shows a lack of dynamic sophistication and your engine will ultimately pay the price. Zipper’s has always believed that power gains should be achieved by improved sophistication and efficiency, not by compromising component reliability. Let Red Shift Cams® create the power that you desire while protecting the investment that you have in your engine and valve train.
