Port area and shim seat geometry decide the damping curve before any adjuster is touched. Port area sets how much oil can pass before the shims begin to lift. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. The alternative to a service part is usually a new damper, which is why this catalogue exists. 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. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 05418-05 in this case. dimension a 5.5 mm, dimension b 44 mm is what distinguishes this number from its neighbours in the range. Needle geometry sets the shape of the adjustable range, not just its size. Valves and needles set the adjustable part of the damping; the piston sets the rest.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 05418-05\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Piston Bands\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 5.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 44 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":53649849909514,"sku":"05418-05","price":55.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05418-05_108017a6-839c-465f-b868-62d3aba269b2.png?v=1788876631","url":"https:\/\/inter-pace.com\/en-jo\/products\/ohlins-piston-ring-5-5-44-machined-05418-05","provider":"Inter-Pace","version":"1.0","type":"link"}
