Small parts are cheap until one of them is missing on a Friday afternoon. Öhlins publishes them in the exploded view so a workshop can order the whole position at once. Thread size and length identify the fastener; substituting a hardware-store equivalent is not sensible in a pressurised damper.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. Suspension is one of the few areas where the original part is genuinely the cheaper decision. If the unit is already apart, compare the published dimensions with the part in your hand. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 21158-01. Where several sizes share a description, only the number separates them. Check dimension a 1 mm, dimension b 4 mm against what you have removed; a close size is not the same part. Thread size and height identify the nut; a taller nut changes the stack height. Lock nuts hold their setting against the vibration a suspension unit lives with.\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 21158-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 4 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":53652551041290,"sku":"21158-01","price":3.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21158-01_ab44e8ed-4ed6-40f9-86fc-e52600e87953.png?v=1788879527","url":"https:\/\/inter-pace.com\/en-pt\/products\/ohlins-nut-lu6m-8-1-4-unc-21158-01","provider":"Inter-Pace","version":"1.0","type":"link"}
