Both diameters and the length are specification, not approximation. Both diameters and the length are specification rather than approximation. Inner and outer diameter both matter; a bushing that is a little loose does more damage than none at all.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Service parts are ordered per piece unless stated otherwise. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21917-04. Öhlins states inner diameter 25.3 mm, outer diameter 44.2 mm, length 145 mm for this number, and those figures are the deciding ones. Sleeves position parts axially and often set the preload on a stack. Öhlins uses PTFE-coated bushings for a low breakaway force.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 21917-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Guides\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 25.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 44.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 145 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":53653009989898,"sku":"21917-04","price":1400.0,"currency_code":"MAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21917-04_a880359c-7b07-4b53-a3b4-3c5e0f63bbf6.png?v=1788880465","url":"https:\/\/inter-pace.com\/en-ma\/products\/ohlins-guide-sleeve-25-3-44-2-145-21917-04","provider":"Inter-Pace","version":"1.0","type":"link"}
