Port area and seat geometry decide the damping before any adjuster is touched. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. The seat face has to be flat enough for the first shim to seal against it.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Where a number has been superseded, Öhlins states the replacement — we pass that on. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21017-10 in this case. Where no measurement is given, the drawing position is what identifies the part. Port area sets how much oil can pass before the shims begin to lift. Piston bands are consumables — they wear against the bore and lose their seal gradually.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 21017-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\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":53652473086218,"sku":"21017-10","price":66.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21017-10_74090163-21f3-495c-878f-87acd43c62b5.png?v=1788879310","url":"https:\/\/inter-pace.com\/en-gi\/products\/ohlins-piston-solid-36-band-assy-21017-10","provider":"Inter-Pace","version":"1.0","type":"link"}
