Öhlins machines its housings from solid rather than casting them, which keeps the bores true. Reservoir housings hold the gas charge and are pressure-rated accordingly. Öhlins anodises housings for corrosion resistance rather than for looks.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eAn original part keeps the unit within its published specification; a near-equivalent quietly moves it. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. We can supply the whole position from the drawing rather than the single piece if that is easier. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21931-09. Check dimension a 1.25 mm, dimension b 4 mm against what you have removed; a close size is not the same part. Housings carry bores for adjusters and seals; their concentricity decides whether the unit seals. Öhlins anodises housings for corrosion resistance rather than for looks.\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 21931-09\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 1.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M8x1.25\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":53653074673930,"sku":"21931-09","price":82.56,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21931-09_6d2cb4bb-de6f-4c5b-8ff8-cfa0218c8fff.png?v=1788880509","url":"https:\/\/inter-pace.com\/products\/ohlins-adaptor-m8x1-25-4-21931-09","provider":"Inter-Pace","version":"1.0","type":"link"}
