Mounting hardware is model-specific — the damper body may be common, the brackets never are. Adaptors let one damper body serve several mounting geometries. Reservoir housings hold the gas charge and are pressure-rated accordingly.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. 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. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21640-01. dimension a 39.5 mm, dimension b 41.45 mm is what distinguishes this number from its neighbours in the range. Öhlins machines its housings from solid rather than casting them, which keeps the bores true. Mounting hardware is model-specific — the damper body may be common, the brackets never are.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 21640-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adaptors\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 39.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 41.45 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":53652641677578,"sku":"21640-01","price":124.73,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21640-01_f7dc33f0-da19-4d3c-9bc8-266a02d6b208.png?v=1788879809","url":"https:\/\/inter-pace.com\/products\/ohlins-adaptor-39-5-41-45-21640-01","provider":"Inter-Pace","version":"1.0","type":"link"}
