{"product_id":"evolution-retro-fit-hydraulic-roller-lifters","title":"Evolution Retro-Fit Hydraulic Roller Lifters","description":"The COMP Cams Evolution Retro-Fit Hydraulic Roller Lifters are engineered for Oldsmobile and Pontiac V8 applications, providing a set of 16 for complete engine coverage. This technology combines a self-contained hydraulic cartridge with reduced oil volume, making them less affected by oil aeration and delivering consistent bleed rates between each lifter.\n\nThe Evolution HCT lifters are built with an incredibly stiff lifter body, which minimizes distortion and ensures reliable hydraulic performance. This bespoke design was developed from the ground up to meet the rigorous performance and durability standards required by high-performance engines. As an added benefit, the hydraulic element of these patented lifters is serviceable, allowing for easier rebuilding in a home garage.\n\nKey specifications include a 0.842 in. OD, 2.475 in. lifter seat height, and a 0.15 in. lifter travel. The retention method is linkbar, and the roller type is needle bearing.","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":52687441199416,"sku":"CCA-85701-16","price":726.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661177454.webp?v=1784884085","url":"https:\/\/store.motormia.co\/products\/evolution-retro-fit-hydraulic-roller-lifters","provider":"MOTORMIA","version":"1.0","type":"link"}
