{"product_id":"392-hemi-5-7l-vvt-stroker-kit-w-molnar-crank-mahle-pistons","title":"392 HEMI 5.7L VVT Stroker Kit w\/ Molnar Crank \u0026 MAHLE Pistons","description":"The Modern Muscle Extreme 392 HEMI 5.7L VVT Based Stroker Kit is a high-performance rotating assembly built to meet demanding engine requirements for naturally aspirated, boosted, or nitrous applications. This kit features a proprietary MAHLE 2618 piston, a Molnar crankshaft, and Molnar connecting rods.\n\nThe core components of the MMX 392 Stroker Rotating Assembly include a Molnar 4.00 stroke crankshaft and a 6.200 connecting rod. It also comes with a Mahle 3.927 custom stroker piston, which has a 15CC dish and is made from 2618 aluminum alloy forgings. The kit includes tool steel pins and a 58-tooth reluctor wheel compatible with 2009-2022 Hemi engines.\n\nKey design features of this kit include an exclusive steel ring package (1mm, 1mm, 2mm) with a Napier second ring for improved oil control, and a Grafal anti-friction coating on the skirts. The top ring land is anodized, and the inverted dome was designed by Modern Muscle Performance. An accumulator groove is machined into the second ring land to collect blow-by gasses, reducing top ring flutter and increasing ring seal. The Molnar premium alloy rods are equipped with 7\/16 proprietary design ARP2000 bolts, and the crankshaft is a full radius design.\n\nInstallation requires professional assistance and clearance confirmation. Additionally, buyers must check local and state laws for emissions compliance before purchasing this product. Optional upgrades include crankshaft balancing, bearing upgrades (coated rod bearings, premium main bearings), a VVT spacer with crank keys, and a windage tray (available for truck or 6.4L base applications). An optional DLC pin upgrade is also available for increased surface hardness and reduced friction.","brand":"Modern Muscle Extreme","offers":[{"title":"Default Title","offer_id":52689274405176,"sku":"MMP-57L-392STRKR","price":2849.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687907735.jpg?v=1784904429","url":"https:\/\/store.motormia.co\/products\/392-hemi-5-7l-vvt-stroker-kit-w-molnar-crank-mahle-pistons","provider":"MOTORMIA","version":"1.0","type":"link"}
