{"product_id":"hydraulic-roller-lifters","title":"Hydraulic Roller Lifters","description":"They feature a cold-forged steel body with heat treatment for exceptional wear resistance, a precision-ground needle roller bearing with a high chromium steel axle for longevity and low friction, and an extra-long cold-forged piston for controlled leak-down and pump-up. The design includes a high-flow, quick-reacting disc-style check valve for better response at higher RPMs and precision oil metering to ensure proper rocker arm lubrication without sacrificing oil pressure.\n\nInstallation of these lifters may typically require a longer pushrod; it is recommended to measure for proper pushrod length. Additionally, the MDS (Multi-Displacement System) must be physically deleted and programmed out of the PCM when using these Johnson lifters. The application is specific to 5.7L, 6.1L, 6.2L, and 6.4L V8 Gen III Hemi models from 2003 and newer, including vehicles like the Chrysler 300 (2005-2023), Dodge Challenger (2008-2023), Dodge Charger (2006-2023), Dodge Durango (2004-2023), Dodge Magnum (2005-2008), Dodge Ram 1500 Pickup (2003-2010), Dodge Ram 2500 Pickup (2003-2010), Dodge Ram 3500 Pickup (2003-2009), Jeep Grand Cherokee (2005-2023), Ram 1500 (2011-2023), Ram 2500 (2011-2023), and Ram 3500 (2011-2023).\n\nRecommended installation steps include inspecting lifters for damage, ensuring rollers spin freely, cleaning the lifter body and engine top end to prevent debris entry, coating the lifter body with engine oil, checking rocker arms and pushrods for wear, installing lifters, setting preload to specifications, and changing the oil and filter after 50 miles to remove any residual debris.","brand":"Johnson","offers":[{"title":"Default Title","offer_id":52662784196920,"sku":"2326R","price":780.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687497740.jpg?v=1784320932","url":"https:\/\/store.motormia.co\/products\/hydraulic-roller-lifters","provider":"MOTORMIA","version":"1.0","type":"link"}
