TWIN CAM® INSTALLATION GUIDE
Thank you for purchasing a set of Red Shift Performance Cams! Red Shift Cams are developed and manufactured to the highest
standards by Zipper’s Performance Products. We grind each cam on custom designed Berco® machines that are the most advanced
in the industry. We control the design, manufacturing and testing processes on site, to provide you with excellent quality control and
batch consistency for a better finished product.
Although the process to make a set of Red Shift Cams is time consuming and painstakingly difficult, no expense is spared in creating
the most accurate and dynamically stable camshafts on the market today. Red Shift Cams will make you smile every time you reach
for the throttle. Red Shift Cams are produced by a team with decades of experience in racing, street riding, and manufacturing
experience. No matter what your application is, Red Shift Cams can help you meet or exceed your performance goals.
The information in this document is meant to share our own engine development discoveries with our customers. These “best
practices" we perform on our engines yield outstanding results in enhancing and strengthening the durability of the Twin Cam®
engine, in any high performance application.
To successfully install a new set of Red Shift Camshafts, the following inspection procedures must be performed to ensure proper
operation of your valve train. The oiling system must be operating correctly for proper valve train control, component reliability, and
the final power output. If you do not have the correct factory Service Manual, obtain one before starting this installation. Be sure to
follow all tear down and assembly instructions, and heed all cautions and warnings presented.
Before beginning the teardown, make sure that you’ve got the proper tools and parts ready to complete the installation.
