Measure the old part against them before ordering. Port area sets how much oil can pass before the shims begin to lift. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\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. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Order by part number. The dimensions below are the ones Öhlins publishes for it. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e05402-05 is the Öhlins number for this position — the same one printed in the service documentation. Check dimension a 6.3 mm, dimension b 1.6 mm against what you have removed; a close size is not the same part. Valves and needles set the adjustable part of the damping; the piston sets the rest. Rebuilding a piston means keeping the shim order, because the stack is the tuning.\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 05402-05\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check Valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 1.6 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":53649781129482,"sku":"05402-05","price":11.91,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05402-05_14be73aa-35f2-46d6-a202-d1f78b5eb40d.png?v=1788876579","url":"https:\/\/inter-pace.com\/products\/ohlins-check-valve-dia-6-3-1-6-05402-05","provider":"Inter-Pace","version":"1.0","type":"link"}
