Fork legs are matched left and right on most Öhlins forks and are listed separately. Fork tubes are the structural part of the front end and carry the braking load into the yokes. Öhlins publishes tube diameters by fork model, and they are not interchangeable across the range.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. The part number is the contract: it defines material, dimension and finish together. The exploded drawing for your unit names the number; if you do not have it, we do. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 21633-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. dimension a 43 mm, dimension b 39.2 mm, dimension c 519 mm is what distinguishes this number from its neighbours in the range. Top caps carry the adjusters and the preload mechanism. Axle clamps and lower legs are machined to hold the axle without distorting the fork.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 21633-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Fork Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 39.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 519 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":53652638531850,"sku":"21633-01","price":897.44,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21633-01_9273d72a-a447-48c6-b933-ebcdd4666e47.png?v=1788879786","url":"https:\/\/inter-pace.com\/products\/ohlins-fork-leg-inner-43-39-2-519-21633-01","provider":"Inter-Pace","version":"1.0","type":"link"}
