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\u003eThickness 0.38 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 12 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 21 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00538-21\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins gives it as 12 mm, 21 mm, 0.38 mm; nothing about that is approximate. Öhlins grinds shims to a flatness tolerance because the faces have to seal against each other. Face flatness matters as much as thickness — a shim that does not seal against its neighbour leaks damping. A stack combines several diameters so the curve changes progressively rather than in steps.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins keeps service parts available for units long after they leave the current price list. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. 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\u003eÖhlins identifies this position by the number 00538-21 in the exploded view for the unit it belongs to. Öhlins states inner diameter 12 mm, outer diameter 21 mm, thickness 0.38 mm for this number, and those figures are the deciding ones. Outer diameter sets the lever the oil works against; thickness sets how hard it resists. The stack is the tuning: outer diameter sets where the shim bends, thickness sets how hard it resists.\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 00538-21\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 12 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 0.38 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":53648846749962,"sku":"00538-21","price":37.2,"currency_code":"MXN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00538-21_8e53bfec-5769-47eb-9f86-bf792eced895.png?v=1788872180","url":"https:\/\/inter-pace.com\/en-mx\/products\/ohlins-shims-12-21-0-38-00538-21","provider":"Inter-Pace","version":"1.0","type":"link"}
