Measure the old part against them before ordering. Mounting hardware is model-specific — the damper body may be common, the brackets never are. Öhlins machines its housings from solid rather than casting them, which keeps the bores true. Housing threads carry the adjusters and are the part that suffers if the adjuster is forced.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Rebuilding to specification only works if the parts are to specification — that starts here. Tell us the damper's model designation and year and we will match the number for you. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21650-09 in this case. Öhlins states dimension a 1 mm, dimension b 41.75 mm, dimension c 17 mm for this number, and those figures are the deciding ones. Clamps have a specified torque; over-tightening distorts the bore they hold. Brackets locate the damper or reservoir against the chassis and take the load in one direction only.\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 21650-09\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 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 41.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 17 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M30x1\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":53652663075082,"sku":"21650-09","price":44.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21650-09_23def5dd-e36a-4962-891d-081316f37218.png?v=1788879872","url":"https:\/\/inter-pace.com\/products\/ohlins-adaptor-ring-m30x1-41-75-17-21650-09","provider":"Inter-Pace","version":"1.0","type":"link"}
