Most seal kits are built around a specific head design. The tube is what the whole damper is built around: everything else references its bore. Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Send us the model and serial number of your unit and we will confirm the position before you order. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21872-01 in the exploded view for the unit it belongs to. This position has no published dimension, so the part number is the only reliable identifier. Tubes are replaced when the bore is marked; polishing them out changes the clearance and makes it worse. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific.\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 21872-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\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":53652898971914,"sku":"21872-01","price":443.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21872-01_5e758e7b-923b-4246-a0ea-e88b61fc5879.png?v=1788880375","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-head-ttx36-21872-01","provider":"Inter-Pace","version":"1.0","type":"link"}
