Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. Valves and needles set the adjustable part of the damping; the piston sets the rest. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. The part number is the contract: it defines material, dimension and finish together. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 15441-01. Where several sizes share a description, only the number separates them. Öhlins states dimension a 27.7 mm, dimension b 16.4 mm, dimension c 4.6 mm for this number, and those figures are the deciding ones. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\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 15441-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 27.7 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 16.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 4.6 mm\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":53649727783178,"sku":"15441-01","price":23.95,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15441-01_35c214f6-50e0-4e2d-ac3b-d785362baf56.png?v=1788876376","url":"https:\/\/inter-pace.com\/en-ch\/products\/ohlins-hydraulic-stop-piston-27-7-16-4-4-6-15441-01","provider":"Inter-Pace","version":"1.0","type":"link"}
