Shaft straightness matters: a bent shaft drags in the seal head and destroys the seal within hours. Shaft diameter sets the displaced volume, which is why it is part of the damper's specification. Adjuster shafts run inside the main shaft on units with a rod-through adjuster.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins keeps service parts available for units long after they leave the current price list. We can supply the whole position from the drawing rather than the single piece if that is easier. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 21000-12 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check diameter 14 mm, length 171.5 mm against what you have removed; a close size is not the same part. A shaft is threaded at both ends: one for the piston, one for the mounting. Shaft diameter sets the volume displaced into the reservoir on every compression stroke.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21000-12\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 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 171.5 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":53652448477450,"sku":"21000-12","price":363.29,"currency_code":"NOK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21000-12_02fc135c-53de-43b7-be76-ce400e8f9bca.png?v=1788879192","url":"https:\/\/inter-pace.com\/en-no\/products\/ohlins-shaft-14-171-5-21000-12","provider":"Inter-Pace","version":"1.0","type":"link"}
