A bent shaft drags in the head and destroys the seal within hours — replace, never straighten. Shaft diameter sets the displaced volume, which is why it is part of the damper's specification. The damper shaft carries the piston and passes through the seal head, so its surface finish decides how long the seals last.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Service parts are ordered per piece unless stated otherwise. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 05509-21. The published dimensions are diameter 16 mm, length 289 mm — measure the old part against them if you are unsure. The damper shaft carries the piston through the oil and out through the seal head. 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\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 05509-21\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 289 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":53649962303754,"sku":"05509-21","price":82.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05509-21_558ff880-5f7c-4dcf-89d5-821b359647e8.png?v=1788876801","url":"https:\/\/inter-pace.com\/en-nl\/products\/ohlins-shaft-16-289-05509-21","provider":"Inter-Pace","version":"1.0","type":"link"}
