Guides and sleeves set the internal alignment of a cartridge. Bushings take the side load so the seal only has to seal. Worn bushings show up as a knock over sharp edges before they show up as a leak.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins keeps service parts available for units long after they leave the current price list. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Send us the model and serial number of your unit and we will confirm the position before you order. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21947-02. inner diameter 25.4 mm, outer diameter 31.5 mm is what distinguishes this number from its neighbours in the range. Inner and outer diameter both matter; a bushing that is a little loose does more damage than none at all. Play at the bushing shows up as a knock over sharp bumps.\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 21947-02\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 25.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 31.5 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":53652146127114,"sku":"21947-02","price":50.58,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21947-02_63b29ade-0f19-4665-8476-249c08639cc1.png?v=1788878135","url":"https:\/\/inter-pace.com\/products\/ohlins-guide-ring-25-4-31-5-21947-02","provider":"Inter-Pace","version":"1.0","type":"link"}
