Guide bushings set the internal alignment of a cartridge. Both diameters and the length are specification rather than approximation. A worn guide shows up as a knock over sharp edges.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Send us the model and serial number of your unit and we will confirm the position before you order. 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\u003eÖhlins identifies this position by the number 21808-01 in the exploded view for the unit it belongs to. inner diameter 27 mm, outer diameter 44.2 mm, length 17 mm is what distinguishes this number from its neighbours in the range. Sleeves position parts axially and often set the preload on a stack. Inner and outer diameter both matter; a bushing that is a little loose does more damage than none at all.\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 21808-01\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 27 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 17 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":53652862796042,"sku":"21808-01","price":365.0,"currency_code":"PGK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21808-01_32b6fa46-b51f-4bf2-bd7f-ee0dd29e8f18.png?v=1788880265","url":"https:\/\/inter-pace.com\/en-pg\/products\/ohlins-guide-ring-27-44-2-17-21808-01","provider":"Inter-Pace","version":"1.0","type":"link"}
