Changing one shim in a stack alters the damping curve measurably; that is why Öhlins sells them individually rather than only as sets.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOuter Diameter 21 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01425-21\u003c\/li\u003e\n\u003cli\u003eInner Diameter 6 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eThickness 0.25 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eDimensionally this is 6 mm, 21 mm, 0.25 mm, which is how it is told apart from the rest of the range. Öhlins holds thickness to hundredths of a millimetre because that is the resolution damping changes at. Öhlins stamps and grinds its shims to tolerances a general-purpose washer never holds. Face flatness matters as much as thickness — a shim that does not seal against its neighbour leaks damping.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 01425-21. inner diameter 6 mm, outer diameter 21 mm, thickness 0.25 mm is what distinguishes this number from its neighbours in the range. Öhlins holds thickness to hundredths of a millimetre because that is the resolution damping changes at. Two shims of the same thickness but different diameter give completely different curves.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 01425-21\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Shims\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 0.25 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":53648557375754,"sku":"01425-21","price":10.16,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01425-21_34524dfc-a287-4a05-9a40-146870a8de7f.png?v=1788871131","url":"https:\/\/inter-pace.com\/en-br\/products\/ohlins-shims-6-21-0-25-01425-21","provider":"Inter-Pace","version":"1.0","type":"link"}
