{"product_id":"6-4l-392-hemi-max-effort-na-performance-camshaft-kit","title":"6.4L 392 HEMI Max Effort NA Performance Camshaft Kit","description":"The MMX Max Effort NA Performance Camshaft is engineered to provide significant power and torque improvements for 6.4L 392 VVT HEMI engines. With full bolt-ons, this camshaft typically yields gains of 50-65 RWHP over the factory profile. It is the largest camshaft offering from MMX that retains compatibility with both stock 8HP70 and NAG1 torque converters and can support nitrous shot sizes up to 200.\n\nTechnical specifications include a .614 intake and exhaust lift with a 112 LSA. Proper installation requires specific hardware, including a VVT camshaft phase limiter kit and aftermarket valve springs. Failure to adjust VVT camshaft tables within the engine tune will result in a significant loss of low-speed torque and horsepower. Long tube headers are recommended to achieve optimal performance results.\n\nThis kit fits 2011-2023 Dodge Charger and Challenger 6.4L, 2011-2023 Chrysler 300 6.4L, 2012-2021 Grand Cherokee SRT 6.4L, and 2018-2026 Durango SRT 6.4L models. Custom tuning is required for proper operation, and users must check local and state laws regarding emissions compliance before purchase.","brand":"MMX","offers":[{"title":"Default Title","offer_id":52689257070904,"sku":"MMP-ME-NA","price":349.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687392458.jpg?v=1784904177","url":"https:\/\/store.motormia.co\/products\/6-4l-392-hemi-max-effort-na-performance-camshaft-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
