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\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKeyed - Keyway cut for cam gear\u003c\/li\u003e\n\u003cli\u003eAlternated firing order reduces engine harmonics\u003c\/li\u003e\n\u003cli\u003eReduces the risk of crankshaft failure due to excessive stress\u003c\/li\u003e\n\u003cli\u003eIncreases intake and exhaust airflow\u003c\/li\u003e\n\u003cli\u003eForged with high-quality chromoly steel\u003c\/li\u003e\n\u003cli\u003eUnlocks power potential \u003c\/li\u003e\n\u003cli\u003e182°\/189° intake\/exhaust duration at 0.050\" tappet lift\u003c\/li\u003e\n\u003cli\u003ePreserves low-RPM performance without sacrificing low-end torque\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e2001-2016 GMC Sierra 2500 3500 6.6L Duramax \u003c\/li\u003e\n\u003cli\u003e2001-2016 Chevrolet Silverado 2500 3500 6.6L Duramax \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePPE Stage 1 Performance Camshaft – Alt Fire Keyed  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e1 Year Limited Warranty  \u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":47605656748189,"sku":"118026110","price":629.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/1_1dc55279-5db8-4fbd-a88a-40d21e6531b7.png?v=1769634830","url":"https:\/\/rudysdiesel.com\/products\/ppe-stage-1-performance-camshaft-alt-fire-keyed-for-2001-2016-gm-6-6l-duramax","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
