The tube is what the whole damper is built around: everything else references its bore. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston. The cylinder is one of the few damper parts that is genuinely wear-limited.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins parts are unit-specific: a close dimension is not a substitute. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 21159-11. Where several sizes share a description, only the number separates them. Öhlins does not publish a dimension here — go by the number and the exploded view. Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against. Head and tube are matched by thread and diameter; neither is interchangeable across units.\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 21159-11\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":53652551303434,"sku":"21159-11","price":696000.0,"currency_code":"MNT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21159-11_1ca5c3f1-7c0a-41e0-bb85-4e9690e9ef90.png?v=1788879529","url":"https:\/\/inter-pace.com\/en-mn\/products\/ohlins-cylinder-head-46-hose-21159-11","provider":"Inter-Pace","version":"1.0","type":"link"}
