A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Order by part number. The dimensions below are the ones Öhlins publishes for it. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e25624-03 is the Öhlins number for this position — the same one printed in the service documentation. Where no measurement is given, the drawing position is what identifies the part. The seat face has to be flat enough for the first shim to seal against it. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.\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 25624-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Jets\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":53653265875210,"sku":"25624-03","price":62000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/25624-03_5160fe4c-4286-4232-9154-2eda1ae6f502.png?v=1788880960","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-top-shaft-jet-4mm-r-t-25624-03","provider":"Inter-Pace","version":"1.0","type":"link"}
