Corrosion on a stored damper usually starts on the exposed shaft. Adjuster shafts run inside the main shaft on units with a rod-through adjuster. The shaft is threaded at both ends: piston at one, mounting at the other.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. If you are between two sizes, send us the measurement and we will check it against the catalogue. Order by part number. The dimensions below are the ones Öhlins publishes for it.\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 — 21021-27 in this case. diameter 17 mm, length 27 mm is what distinguishes this number from its neighbours in the range. Chrome or nitride treatment is what lets the shaft run in a seal for thousands of kilometres. Öhlins hardens and surface-treats its shafts because a scratch on the running surface takes the seal with it.\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 21021-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Damper Shafts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 17 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 27 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M17\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":53652475609354,"sku":"21021-27","price":241.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21021-27_fcc12ca6-42c0-4a57-a0f2-20f15b65a74e.png?v=1788879324","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-shaft-extension-14-m17-27-21021-27","provider":"Inter-Pace","version":"1.0","type":"link"}
