Measure the old part against them before ordering. Revalving means changing the stack, not the piston — that is why shims are sold singly. Outer diameter sets the lever the oil works against; thickness sets how hard it resists. Two shims of the same thickness but different diameter give completely different damping.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Tell us the damper's model designation and year and we will match the number for you. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 00520-18. Where several sizes share a description, only the number separates them. Öhlins states inner diameter 12 mm, outer diameter 18 mm, thickness 0.20 mm for this number, and those figures are the deciding ones. Outer diameter sets the lever the oil works against; thickness sets how hard it resists. 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\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 00520-18\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 18 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":53648824336650,"sku":"00520-18","price":2.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00520-18_454b4750-832a-40e8-a13b-61914f0b6fdc.png?v=1788872049","url":"https:\/\/inter-pace.com\/en-gr\/products\/ohlins-shims-12-18-0-20-00520-18","provider":"Inter-Pace","version":"1.0","type":"link"}
