The piston carries the shim stacks and meters the oil through its ports.\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 21015-02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eÖhlins publishes no separate dimension for this position, so the part number carries the identity. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21015-02. Öhlins does not publish a dimension here — go by the number and the exploded view. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\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 21015-02\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":53652471480586,"sku":"21015-02","price":19.22,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21015-02_9036b575-05c5-434f-99c4-c0e39bcb702c.png?v=1788879300","url":"https:\/\/inter-pace.com\/en-it\/products\/ohlins-piston-solid-36-21015-02","provider":"Inter-Pace","version":"1.0","type":"link"}
