The shaft is threaded at both ends: piston at one, mounting at the other. Shafts are not shortened or extended; the length is the specification. Corrosion on a stored damper usually starts on the exposed shaft.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. The alternative to a service part is usually a new damper, which is why this catalogue exists. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 05500-31. Where several sizes share a description, only the number separates them. Öhlins states diameter 16 mm, length 178 mm for this number, and those figures are the deciding ones. The damper shaft carries the piston and passes through the seal head, so its surface finish decides how long the seals last. 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\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 05500-31\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 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 178 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":53649212735754,"sku":"05500-31","price":80.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05500-31_78a0267c-2654-4698-b67d-84baa505646a.png?v=1788874258","url":"https:\/\/inter-pace.com\/en-sg\/products\/ohlins-shaft-16-178-05500-31","provider":"Inter-Pace","version":"1.0","type":"link"}
