Circlips hold axial position under load; a sprung one lets the assembly walk. A spacer that is a millimetre short changes the preload on a shim stack, and with it the damping. Öhlins specifies thread-locking compound by position; not every fastener wants it.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Order by part number. The dimensions below are the ones Öhlins publishes for it. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21603-01 is the Öhlins number for this position — the same one printed in the service documentation. The thread is M10x1.25. Fasteners in a damper see pressure, heat and vibration at once, which is why the grade matters. A plug that seals a gas port is a pressure part despite its size.\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 21603-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Plugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M10x1.25\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":53652578795786,"sku":"21603-01","price":238.0,"currency_code":"PGK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21603-01_3dce5fe3-1f07-419d-84cc-48967a3d44ce.png?v=1788879615","url":"https:\/\/inter-pace.com\/en-pg\/products\/ohlins-base-plug-m10x1-25-21603-01","provider":"Inter-Pace","version":"1.0","type":"link"}
