Measure the old part against them before ordering. A worn or bent shim shows up as damping that has quietly drifted from the setting sheet. Shim thickness is measured in hundredths of a millimetre because that is the resolution at which damping force changes. A shim is a thin steel washer, and a stack of them is what actually generates damping in an Öhlins unit — the oil has to bend them out of the way to pass.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins parts are unit-specific: a close dimension is not a substitute. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 00520-30 in the exploded view for the unit it belongs to. Check inner diameter 12 mm, outer diameter 30 mm, thickness 0.20 mm against what you have removed; a close size is not the same part. A shim is a thin, ground steel washer, and the stack of them is what generates damping. Öhlins holds thickness to hundredths of a millimetre because that is the resolution damping changes at.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 00520-30\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 30 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":53646920646922,"sku":"00520-30","price":3.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00520-30_640d446b-5bb9-470d-9133-aad2eedc9ffe.png?v=1788869508","url":"https:\/\/inter-pace.com\/en-zw\/products\/ohlins-shims-12-30-0-20-00520-30","provider":"Inter-Pace","version":"1.0","type":"link"}
