It features aggressive lobes with 217\/23X duration, .644\"\/.644\" lift, and a 114 LSA, with a 32% fuel lobe and 0.05220\" intake lobe lift at TDC. Extensive testing has shown this camshaft to provide superior valve train stability and greater horsepower and torque gains compared to competitor designs, leading to improved longevity and reduced wear.\n\nThis Stage 4 grind is a popular choice for enthusiasts looking to delete the DOD\/AFM system or enhance the performance of their truck's engine. It maintains OEM driving characteristics and pairs well with an upgraded torque converter. It represents BTR's largest recommended camshaft for the L83 engine when using unmilled cylinder heads.\n\nBy leveraging the factory VVT system, this camshaft allows for precise tuning of valve events, delivering robust low-end torque for towing and substantial top-end power for spirited driving. This dual-purpose capability provides users with the best of both worlds. For optimal performance and to ensure proper operation, a valve spring upgrade (part number SK013) is required.\n\nThis camshaft is designed for 2014+ L83 and L86 engines and is compatible with the factory-installed VVT system. For those with 2014 - early 2019 L83\/L86 engines, a VVT limiter may be necessary, while 2019+ L84\/L87 engines may require a different VVT limiter.","brand":"Brian Tooley","offers":[{"title":"Default Title","offer_id":52687286632760,"sku":"BTR-GENVSTAGE4","price":409.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660190274.jpg?v=1784882258","url":"https:\/\/store.motormia.co\/products\/gen-v-truck-stage-4-camshaft-217-23x-644-644-114-lsa","provider":"MOTORMIA","version":"1.0","type":"link"}
