Öhlins offers several lengths per diameter because stroke differs by model. Shafts are not shortened or extended; the length is the specification. Shaft diameter sets the displaced volume, which is why it is part of the damper's specification.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Order by part number — descriptions repeat across sizes, numbers do not. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21756-01 in the exploded view for the unit it belongs to. The published dimensions are diameter 0.75 mm, length 55.5 mm — measure the old part against them if you are unsure. A shaft is measured by diameter and overall length, and both are specific to the unit it belongs to. Shaft diameter sets the displaced volume, which is why it is part of the damper's specification.\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 21756-01\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 0.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 55.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M12x0.75\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":53652832420106,"sku":"21756-01","price":6000.0,"currency_code":"DZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21756-01_d7fb5e52-45c3-4d64-b06a-4de5ac69427b.png?v=1788880191","url":"https:\/\/inter-pace.com\/en-dz\/products\/ohlins-shaft-extension-m12x0-75-55-5-21756-01","provider":"Inter-Pace","version":"1.0","type":"link"}
