Both diameters and the length are specification, not approximation. Inner and outer diameter both matter; a bushing that is a little loose does more damage than none at all. Öhlins uses low-friction coated bushings so the unit breaks away smoothly rather than sticking.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. We can check the number against the Öhlins exploded view before you order — just ask. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e21978-06 is the Öhlins number for this position — the same one printed in the service documentation. Check inner diameter 31 mm, outer diameter 36.5 mm against what you have removed; a close size is not the same part. Play at the bushing shows up as a knock over sharp bumps. Bushings carry the side load in a damper or fork and keep the moving parts concentric.\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 21978-06\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 36.5 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":53653161410826,"sku":"21978-06","price":396.51,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21978-06_5eec10ca-5fbc-4e3e-9707-06a90f4514dd.png?v=1788880608","url":"https:\/\/inter-pace.com\/en-dk\/products\/ohlins-guide-ring-31-36-5-21978-06","provider":"Inter-Pace","version":"1.0","type":"link"}
