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

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.
