Needle geometry sets the shape of the adjustable range, not just its size.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 15418-03\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\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. If it sticks open, the damper loses low-speed damping entirely. Piston bands are consumables — they wear against the bore and lose their seal gradually. A check valve lets oil refill the working chamber without passing the shim stack.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. If the unit is already apart, compare the published dimensions with the part in your hand. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 15418-03 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins does not publish a dimension here — go by the number and the exploded view. The seat face has to be flat enough for the first shim to seal against it. 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\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 15418-03\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":53652325662986,"sku":"15418-03","price":60.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15418-03_5cca153e-6f10-4502-b7f3-5e0e760c6eee.png?v=1788878741","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-check-valve-holder-fgmx-15418-03","provider":"Inter-Pace","version":"1.0","type":"link"}
