Jets meter fixed bleed flow and are sized in tenths of a millimetre. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable. Port area sets how much oil can pass before the shims begin to lift.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. 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. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 15441-05 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states dimension a 27.2 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 through its ports. Port area and shim seat geometry decide the damping curve before any adjuster is touched.\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 15441-05\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 27.2 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":53652346634506,"sku":"15441-05","price":2800.0,"currency_code":"BDT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15441-05_64ea3f9a-6e3f-415c-9cae-63e6440aa5f7.png?v=1788878839","url":"https:\/\/inter-pace.com\/en-bd\/products\/ohlins-hydr-stop-piston-27-2-16-4-4-6-15441-05","provider":"Inter-Pace","version":"1.0","type":"link"}
