The shaft is threaded at both ends: piston at one, mounting at the other. Corrosion on a stored damper usually starts on the exposed shaft. A bent shaft drags in the head and destroys the seal within hours — replace, never straighten.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Service parts are ordered per piece unless stated otherwise. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21637-09 in the exploded view for the unit it belongs to. The published dimensions are diameter 12 mm, length 468 mm — measure the old part against them if you are unsure. The polished section runs in the seal; a mark there ends the seal's life. Its polished section runs directly in the seal, so any mark there ends the seal's life quickly.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 21637-09\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 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 468 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":53650785501450,"sku":"21637-09","price":241.0,"currency_code":"QAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21637-09_3b8b11f4-f877-46e8-be23-7251c15b86ef.png?v=1788877381","url":"https:\/\/inter-pace.com\/en-qa\/products\/ohlins-shaft-12-468-alu-21637-09","provider":"Inter-Pace","version":"1.0","type":"link"}
