Port area sets how much oil can pass before the shims begin to lift. Öhlins machines its pistons so the port edges stay sharp and the flow predictable. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Where a number has been superseded, Öhlins states the replacement — we pass that on. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e06004-11 is the Öhlins number for this position — the same one printed in the service documentation. This position has no published dimension, so the part number is the only reliable identifier. Valves and needles set the adjustable part of the damping; the piston sets the rest. 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\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 06004-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\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":53650573656330,"sku":"06004-11","price":110500.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/06004-11_c28b889f-60e0-4e4b-88cc-d84da01bb115.png?v=1788877271","url":"https:\/\/inter-pace.com\/en-ci\/products\/ohlins-piston-cup-linear-40mm-alum-06004-11","provider":"Inter-Pace","version":"1.0","type":"link"}
