{"product_id":"hydraulic-roller-lifters-2","title":"Hydraulic Roller Lifters","description":"The COMP Cams 851-16 is a set of 16 hydraulic roller lifters engineered to enhance engine performance and durability. As a direct upgrade from stock hydraulic roller lifters, or as a crucial component in a retro-fit for non-roller engine blocks (requiring COMP Cams Retro-Fit Kit part #31-1000), these lifters are designed to optimize engine operation.\n\nThese lifters feature a standard .875-inch diameter and a 2.60-inch seat height, with each lifter weighing 135 grams. The integrated roller wheel significantly decreases friction compared to traditional flat tappet lifters, leading to increased longevity and reliability of the valvetrain. Furthermore, their design allows them to accommodate more aggressive camshaft profiles, which is essential for unlocking higher performance ceilings in performance-oriented builds.\n\nBy reducing friction and enabling more aggressive cam profiles, the COMP Cams 851-16 lifters contribute to improved engine efficiency and power output. They are a key component for enthusiasts looking to maximize the potential of their Small Block Ford 302c.i. engines originally equipped with hydraulic roller cams, or for those modifying non-roller 289-302 Small Block, 351 Windsor, and Cleveland engines.","brand":"Comp Cams","offers":[{"title":"Default Title","offer_id":52687443198264,"sku":"COM851-16","price":286.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661177505.webp?v=1784884106","url":"https:\/\/store.motormia.co\/products\/hydraulic-roller-lifters-2","provider":"MOTORMIA","version":"1.0","type":"link"}
