A shim is a thin steel washer, and a stack of them is what actually generates damping in an Öhlins unit — the oil has to bend them out of the way to pass.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOuter Diameter 28 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00187-28\u003c\/li\u003e\n\u003cli\u003eInner Diameter 8 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\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003e00187-28 is the 8 mm, 28 mm, 0.25 mm version — Öhlins lists each size separately. Two shims of the same thickness but different diameter give completely different damping. Changing one shim in a stack alters the damping curve measurably; that is why Öhlins sells them individually rather than only as sets. Revalving means changing the stack, not the piston — that is why shims are sold singly.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. The part number is the contract: it defines material, dimension and finish together. Öhlins parts are unit-specific: a close dimension is not a substitute. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 00187-28 in the exploded view for the unit it belongs to. Öhlins states inner diameter 8 mm, outer diameter 28 mm, thickness 0.25 mm for this number, and those figures are the deciding ones. Shim thickness is measured in hundredths of a millimetre because that is the resolution at which damping force changes. A stack combines several diameters so the curve changes progressively rather than in steps.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 00187-28\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 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 28 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":53648658039050,"sku":"00187-28","price":37.09,"currency_code":"MXN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00187-28_fcfe6760-690c-482d-b7c7-64363a3d6b00.png?v=1788871392","url":"https:\/\/inter-pace.com\/en-mx\/products\/ohlins-shims-8-28-0-25-00187-28","provider":"Inter-Pace","version":"1.0","type":"link"}
