Face flatness matters as much as thickness — a shim that does not seal against its neighbour leaks damping. Shims are reused only if they are undamaged and flat; a coned shim is finished. Outer diameter sets the lever the oil works against; thickness sets how hard it resists.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Service parts are supplied per piece unless the description says otherwise. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e00520-27 is the Öhlins number for this position — the same one printed in the service documentation. Check inner diameter 12 mm, outer diameter 27 mm, thickness 0.20 mm against what you have removed; a close size is not the same part. Öhlins stamps and grinds its shims to tolerances a general-purpose washer never holds. Changing one shim in a stack alters the damping curve measurably; that is why Öhlins sells them individually rather than only as sets.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 00520-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Shims\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 27 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 0.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53646917075210,"sku":"00520-27","price":500.0,"currency_code":"GYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00520-27_c2a47c14-0c93-4992-a8c4-1be7ca9917e8.png?v=1788869505","url":"https:\/\/inter-pace.com\/en-gy\/products\/ohlins-shims-12-27-0-20-00520-27","provider":"Inter-Pace","version":"1.0","type":"link"}
