{"product_id":"mcs900186","title":"Eastern 53-84 Hydraulic Unit – 1953–1965 Panhead; 1966–1984 Shovelhead","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eOEM reproduction hydraulic unit. Replacement for 17920-53A. 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.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003e53-65 Panhead; 66-84 Shovelhead (NU)\u003c\/p\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Eastern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e MOTOR PARTS \u0026gt; HYDRAULIC UNITS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 900186\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePart Numbers\u003c\/h2\u003e\n\u003cp\u003eMCS Part Number: 900186\u003cbr\u003eManufacturer Part Number: A-17920-53A\u003cbr\u003eOEM Number: 17920-53A\u003c\/p\u003e","brand":"Eastern","offers":[{"title":"Default Title","offer_id":57361497227651,"sku":"MCS900186","price":57.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/900451k_6e3938a5-e22e-4ed0-8eb1-159d7afd1f3d.jpg?v=1785947286","url":"https:\/\/hogparts.co.uk\/products\/mcs900186","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
