Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05665-18\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Port area sets how much oil can pass before the shims begin to lift. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Rebuilding a piston means keeping the shim order, because the stack is the tuning.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins keeps service parts available for units long after they leave the current price list. The part number is the contract: it defines material, dimension and finish together. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. 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.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 05665-18 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins does not publish a dimension here — go by the number and the exploded view. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Port area sets how much oil can pass before the shims begin to lift.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 05665-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e 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":53649250386186,"sku":"05665-18","price":28.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05665-18_d9507352-821e-4c7c-9e01-a564b91999e6.png?v=1788874492","url":"https:\/\/inter-pace.com\/en-bg\/products\/ohlins-valve-assy-dia-1-8-bleed-3-2-05665-18","provider":"Inter-Pace","version":"1.0","type":"link"}
