Öhlins offers several lengths per diameter because stroke differs by model. Surface hardness is what lets the shaft survive thousands of cycles through a seal. This is a part that is replaced rather than repaired.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Öhlins keeps service parts available for units long after they leave the current price list. Send us the model and serial number of your unit and we will confirm the position before you order. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21637-08 in the exploded view for the unit it belongs to. Öhlins states diameter 12 mm, length 528 mm for this number, and those figures are the deciding ones. The polished section runs in the seal; a mark there ends the seal's life. Chrome or nitride treatment is what lets the shaft run in a seal for thousands of kilometres.\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 21637-08\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 528 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":53652640989450,"sku":"21637-08","price":156.83,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21637-08_fce03b33-338d-42a9-9028-f0ce1601b15d.png?v=1788879804","url":"https:\/\/inter-pace.com\/en-be\/products\/ohlins-shaft-12-528-alu-21637-08","provider":"Inter-Pace","version":"1.0","type":"link"}
