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’’ 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.
Features:
Alternated firing order reduces engine harmonics Reduces the risk of crankshaft failure due to excessive stress Increases intake and exhaust airflow Forged with high-quality chromoly steel Unlocks power potential 182°/189° intake/exhaust duration at 0.050" tappet lift Preserves low-RPM performance without sacrificing low-end torque Compatible Vehicles:2016 Chevrolet Silverado 2500HD 8 Cyl 6.6 Liter Turbo
