Port area sets how much oil can pass before the shims begin to lift.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 15090-03\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThere is no measurement to check here — the number and the exploded view identify it. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 15090-03 in the exploded view for the unit it belongs to. Öhlins does not publish a dimension here — go by the number and the exploded view. Needle geometry sets the shape of the adjustable range, not just its size. Öhlins uses a light spring so the valve reacts to shaft speed rather than to pressure alone.\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 15090-03\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":53649569710346,"sku":"15090-03","price":123.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15090-03_ef3b08df-3130-47bc-a0ca-d5df7470f7d9.png?v=1788876078","url":"https:\/\/inter-pace.com\/en-ht\/products\/ohlins-check-valve-housing-15090-03","provider":"Inter-Pace","version":"1.0","type":"link"}
