Any mark on the polished section is a reason to replace rather than to reassemble. Shaft diameter sets the volume displaced into the reservoir on every compression stroke. A shaft is threaded at both ends: one for the piston, one for the mounting.\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 tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. If you are between two sizes, send us the measurement and we will check it against the catalogue. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e15011-31 is the Öhlins number for this position — the same one printed in the service documentation. Check diameter 16 mm, length 178 mm against what you have removed; a close size is not the same part. Shafts are not shortened or extended; the length is the specification. Öhlins offers shafts in several lengths per diameter because the stroke differs by model.\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 15011-31\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":53649541005578,"sku":"15011-31","price":114.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15011-31_56dfdf56-3e64-45bf-a00f-553609041451.png?v=1788875934","url":"https:\/\/inter-pace.com\/en-na\/products\/ohlins-shaft-16-178-15011-31","provider":"Inter-Pace","version":"1.0","type":"link"}
