{"product_id":"pro-series-hydraulic-roller-lifters","title":"Pro Series Hydraulic Roller Lifters","description":"The Morel 4602 Pro Series hydraulic roller lifters are engineered for performance and high RPM applications in Small Block Chevy engines. Constructed with a durable billet body, these lifters are designed to withstand the demands of engines capable of reaching 7000 RPM.\n\nEach lifter features a .750-inch diameter roller wheel for reduced friction and improved longevity. The plunger travel is set at .120 inches, providing a precise response. These lifters also boast an 80% fill rate with test oil, contributing to consistent performance. Recommended spring pressures are 100-200 lbs for seat pressure and 280-400 lbs for open pressure.\n\nDesigned for Small Block Chevy V8 engines with displacements from 262 to 400 cubic inches, these lifters have a standard .842-inch body diameter. The Pro Series design includes a clipped axle and tie-bars, intended for use in stock racing classes where some plunger travel is acceptable and contributing to a more solid valve train feel.","brand":"Morel","offers":[{"title":"Default Title","offer_id":52663026778424,"sku":"MOR-4602","price":979.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687510905.webp?v=1784322971","url":"https:\/\/store.motormia.co\/products\/pro-series-hydraulic-roller-lifters","provider":"MOTORMIA","version":"1.0","type":"link"}
