The damper shaft carries the piston and passes through the seal head, so its surface finish decides how long the seals last. A shaft is measured by diameter and overall length, and both are specific to the unit it belongs to. This is a part that is replaced rather than repaired.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21023-07 in the exploded view for the unit it belongs to. Öhlins states diameter 17 mm, length 58 mm for this number, and those figures are the deciding ones. This is a part that is replaced rather than repaired. Adjuster shafts run inside the main shaft on units with a rod-through adjuster.\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 21023-07\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 58 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M13x1\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":53652476952842,"sku":"21023-07","price":117.0,"currency_code":"AZN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21023-07_ac393907-9e34-43d5-beea-b5ee00467d0e.png?v=1788879331","url":"https:\/\/inter-pace.com\/en-az\/products\/ohlins-shaft-extension-m13x1-m17-58-21023-07","provider":"Inter-Pace","version":"1.0","type":"link"}
