2001-2016 Duramax SoCal Alternative Firing Order Camshaft (6480AF)
Extend the life of your crankshaft by changing the firing order of your engine.
The OEM firing order ends with cylinder 3 and begins with cylinders 1 and 2. The result is a 3-1-2 hit to the crankshaft. Duramax cranks have a tendency to break right behind the first rod throw at the intersection of the second main journal, right where the 3-1-2 hit would stress the crankshaft the most. Coincidence? We think not.
After carefully researching the different firing orders available to a V-8 engine, SoCal Diesel was the first to implement this "Alternative Firing Order" camshaft for the Duramax engine. In moving cylinders 3, 1 and 2 away from each other, we have significantly extended the abuse the crankshaft can withstand.
Swapping a few pins in the wiring harness will insure the ECM sends the injector signal to the correct cylinder. Wiring diagrams and instructions are included with every purchase.
