SoCal Diesel Standard Firing Order Duramax Camshaft (2001-2016)

The camshaft is an integral part of your engines breathing characteristics.
The camshaft lobe profiles need to be carefully matched to the rest of the engine components in order to achieve maximum performance for any given application.
We have designed profiles to meet many different applications that include dedicated Drag Racing and Sled Pulling.
