The Empire Performance EPE-Cam66-100X Camshaft w/ Alternated Firing Order for your 01-14 GM 6.6L Duramax is the first of its type. Empire Performance Engineering was the first in development of a custom billet camshaft w/ alternated firing order for the Duramax trucks. The alternate fire pattern of the cam shaft is a large step in the right direction to solve to all so troublesome Duramax crank shaft failures at all horse power levels. By rearranging the firing order it allows for lower harmonics of the motor and relieves stress off the front area half of the crank shaft where most stress is found.
Our cam profiles can be found in the leading competition Duramax trucks around the world. All cams are ground to EPE specifications per application. Note: The stage 1 - 4 cams are priced the same but are not suggested to be used on trucks that do not meet certain specifications. "Ex. Using a Stage 3 cam on a low boosted application can result in the term "over cam motor" and performance will suffer." All cams are designed for particular applications as well as having the ability to create a cam profile to meet your particular application.
