Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 15510-01\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. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. A check valve lets oil refill the working chamber without passing the shim stack. Valves and needles set the adjustable part of the damping; the piston sets the rest.\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 supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Öhlins parts are unit-specific: a close dimension is not a substitute. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e15510-01 is the Öhlins number for this position — the same one printed in the service documentation. Where no measurement is given, the drawing position is what identifies the part. Port area and shim seat geometry decide the damping curve before any adjuster is touched. 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\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 15510-01\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":53649777262858,"sku":"15510-01","price":19.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15510-01_f379df9c-ea6f-4f38-99ca-929594bd44ea.png?v=1788876558","url":"https:\/\/inter-pace.com\/en-ht\/products\/ohlins-check-valve-housing-15510-01","provider":"Inter-Pace","version":"1.0","type":"link"}
