This is a part that is replaced rather than repaired. Öhlins offers shafts in several lengths per diameter because the stroke differs by model. Corrosion on a stored damper usually starts on the exposed shaft.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. The part number is the contract: it defines material, dimension and finish together. Service parts are ordered per piece unless stated otherwise. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e21812-15 is the Öhlins number for this position — the same one printed in the service documentation. diameter 8 mm, length 424 mm is what distinguishes this number from its neighbours in the range. The shaft is threaded at both ends: piston at one, mounting at the other. The damper shaft carries the piston through the oil and out through the seal head.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 21812-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Damper Shafts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 424 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":53652867907850,"sku":"21812-15","price":122.21,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21812-15_38e7817e-7431-43b9-9f00-504b498e63cf.png?v=1788880280","url":"https:\/\/inter-pace.com\/products\/ohlins-shaft-8-424-21812-15","provider":"Inter-Pace","version":"1.0","type":"link"}
