Most seal kits are built around a specific head design. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. The tube is what the whole damper is built around: everything else references its bore.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Order by part number. The dimensions below are the ones Öhlins publishes for it. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21898-01. Öhlins does not publish a dimension here — go by the number and the exploded view. Head and tube are matched by thread and diameter; neither is interchangeable across units. The cylinder is one of the few damper parts that is genuinely wear-limited.\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 21898-01\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":53652909424906,"sku":"21898-01","price":168.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21898-01_235bf3ea-89f8-4e11-91db-6e37add065da.png?v=1788880408","url":"https:\/\/inter-pace.com\/en-sr\/products\/ohlins-cylinder-head-ttx36-21898-01","provider":"Inter-Pace","version":"1.0","type":"link"}
