PPE 118026110 2001-2016 GM 6.6L DURAMX STAGE 1 PERFORMANCE CAMSHAFT ALT FIRE PERFORMANCE

The PPE Stage 1 Performance Camshaft - ALT-Firing changes the cylinder firing sequence to 1-5-6-3-4-2-7-8. This alternation reduces the stress exerted on the crankshaft and prevents crankshaft failures which are commonly seen in high-performance applications.

With a moderate intake/exhaust duration and a .460 inch intake/exhaust valve lift, this camshaft works great with stock or performance tune.

Each camshaft is forged with high-tensile chromoly steel, precision ground to extremely tight tolerance, and then carburized and quenched to achieve 60+ HRC surface hardness.

It also features a slotted gear alignment pin for increased durability.
