Both diameters and the length are specification rather than approximation. Guide bushings set the internal alignment of a cartridge. Bushings take the side load so the seal only has to seal.\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. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Tell us the damper's model designation and year and we will match the number for you. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21669-03 in the exploded view for the unit it belongs to. inner diameter 31 mm, outer diameter 42.5 mm is what distinguishes this number from its neighbours in the range. Bushings carry the side load in a damper or fork and keep the moving parts concentric. Worn bushings show up as a knock over sharp edges before they show up as a leak.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 21669-03\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 31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 42.5 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":53652743618826,"sku":"21669-03","price":456.8,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21669-03_39eaade0-8093-41da-9b07-b0efbd718a9e.png?v=1788880075","url":"https:\/\/inter-pace.com\/en-dk\/products\/ohlins-guide-ring-upper-31-42-5-21669-03","provider":"Inter-Pace","version":"1.0","type":"link"}
