Katech Torquer LS3 Camshaft

Katech, Inc. has been in the racing industry for 25 years and knows that the key to a winning engine is the camshaft. Not only do our camshaft packages make great power, but the durability on them is second to none. What makes our camshafts so great is our ability to analyze the valve while it is in motion on our Optron spin c

ell. This is a claim that few people in the industry can make, especially since we were one of the first companies to use this technology. With our involvement in the C5-R race program, we can safely claim that there has never once been a failure due to insufficient valvetrain design.

What this means is you will get the most durable, highest revving cam package that is on the market today. You can also be assured that every aspect of the camshaft has been designed for great power and superb driveability.

Note: This is a 3-bolt camshaft. If you are installing it in a newer application such as the 2010 Camaro LS3, you'll need to change the camshaft sprocket to the 3-bolt version. This can be found on the LS7 (3-bolt, 4x trigger), part number 12586481.
