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. Öhlins offers shafts in several lengths per diameter because the stroke differs by model.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. Every part in this catalogue is one Öhlins fits itself during assembly and service. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. 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\u003eÖhlins identifies this position by the number 21020-20 in the exploded view for the unit it belongs to. Check diameter 1 mm, length 65 mm against what you have removed; a close size is not the same part. Shaft diameter sets the volume displaced into the reservoir on every compression stroke. Shafts are not shortened or extended; the length is the 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 21020-20\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 1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 65 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M13x1\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":53652474364170,"sku":"21020-20","price":64.55,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21020-20_e32b5a39-65cd-4565-8b25-78a512b2331d.png?v=1788879319","url":"https:\/\/inter-pace.com\/en-gi\/products\/ohlins-shaft-extension-m13x1-m17x1-65-21020-20","provider":"Inter-Pace","version":"1.0","type":"link"}
