{"product_id":"hydraulic-tappets-big-twin","title":"Hydraulic Tappets - Big Twin","description":"Rollers have a larger-than-stock inner bearing race that reduces stress and increases axle life. Each lifter body and plunger assembly is hand-fit and pressure-tested to ensure correct operation. Redesigned plunger assembly withstands forces associated with heavy-duty valve springs and pushrods typically used in high-performance applications. Revised metering device precisely controls oil delivery to top end, ensuring rapid lifter pump-up and reducing possibility of oil starvation to bottom end. Tappets that include the HL²T Limited Travel Kit improve cold starts and high rpm valve timing accuracy.","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44419619455021,"sku":"FJHF_33-5352","price":381.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/4057\/5021\/files\/09290004_0.png?v=1765752402","url":"https:\/\/shopronayers.com\/products\/hydraulic-tappets-big-twin","provider":"Ron Ayers Motorsports","version":"1.0","type":"link"}
