{"product_id":"s-s-53-84-hydraulic-unit","title":"S\u0026S, 53-84 hydraulic unit","description":"OEM reproduction hydraulic unit. Can be used as stock replacement for S\u0026amp;S 512881\/512882 tappet sets. Also fits as a direct OEM replacement for 17920-53A hydraulic unit.   Note: Will not fit S\u0026amp;S SH-series (Shovel style) engines.  Note: The early style hydraulic tappets sets can be purchased as a set (hydraulic unit + tappet body with roller) or as individual parts.  When purchasing individual parts correct tolerance cannot be guaranteed; which can influence hydraulic function. Dealers with a larger stock can mix and match hydraulic units and tappet bodies to compose a set that offers excellent bleed-down times. For all others it is advised to go for a complete hydraulic unit and tappet body assembly from the same manufacturer; as S\u0026amp;S or JIMS offer. These are machined with the correct tolerance relative to each other to work correctly right out of the box.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 53-65 Panhead; 66-84 Shovelhead (NU)\u003c\/p\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":54307914285383,"sku":"512886","price":177.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7812\/0519\/files\/512886k.jpg?v=1784486159","url":"https:\/\/www.chopperessentials.com\/products\/s-s-53-84-hydraulic-unit","provider":"Chopper Essentials Co.","version":"1.0","type":"link"}
