Two shims of the same thickness but different diameter give completely different curves. Öhlins stamps and grinds its shims to tolerances a general-purpose washer never holds. A coned or marked shim is finished — it no longer seals against its neighbour.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. The alternative to a service part is usually a new damper, which is why this catalogue exists. Öhlins parts are unit-specific: a close dimension is not a substitute. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 00187-21 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states inner diameter 8 mm, outer diameter 21 mm, thickness 0.25 mm for this number, and those figures are the deciding ones. Two shims of the same thickness but different diameter give completely different curves. A worn or bent shim shows up as damping that has quietly drifted from the setting sheet.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 00187-21\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 8 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":53646864220426,"sku":"00187-21","price":300.0,"currency_code":"BDT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00187-21_81d83eee-d0aa-4a3b-a2c2-baeb73540299.png?v=1788868866","url":"https:\/\/inter-pace.com\/en-bd\/products\/ohlins-shims-8-21-0-25-00187-21","provider":"Inter-Pace","version":"1.0","type":"link"}
