Valves and needles set the adjustable part of the damping; the piston sets the rest. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. We can check the number against the Öhlins exploded view before you order — just ask. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 15489-03 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Where no measurement is given, the drawing position is what identifies the part. Needle geometry sets the shape of the adjustable range, not just its size. The seat face has to be flat enough for the first shim to seal against it.\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 15489-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check Valves\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":53649764352266,"sku":"15489-03","price":26.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15489-03_469425fb-19fe-44a8-bc07-3faa6611557a.png?v=1788876514","url":"https:\/\/inter-pace.com\/en-ht\/products\/ohlins-check-valve-housing-15489-03","provider":"Inter-Pace","version":"1.0","type":"link"}
