The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Needle geometry sets the shape of the adjustable range, not just its size. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. If the unit is already apart, compare the published dimensions with the part in your hand. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 05981-12 in the exploded view for the unit it belongs to. Öhlins does not publish a dimension here — go by the number and the exploded view. Port area sets how much oil can pass before the shims begin to lift. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 05981-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check 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":53650538332426,"sku":"05981-12","price":489000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05981-12_0cb403f0-89a7-4b98-9d85-f24cee7039bf.png?v=1788877253","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-check-valve-assy-reb-close-1-2-05981-12","provider":"Inter-Pace","version":"1.0","type":"link"}
