Öhlins grinds shims to a flatness tolerance because the faces have to seal against each other.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 00538-31\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 31 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eThickness 0.38 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 12 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThis one measures 12 mm, 31 mm, 0.38 mm, and those figures are what separate it from the neighbouring numbers. 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. The stack is the tuning: outer diameter sets where the shim bends, thickness sets how hard it resists. A worn or bent shim shows up as damping that has quietly drifted from the setting sheet.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\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 tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 00538-31 in this case. Öhlins states inner diameter 12 mm, outer diameter 31 mm, thickness 0.38 mm for this number, and those figures are the deciding ones. Suspension technicians keep these in stock by size because a revalve means changing several at once. 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\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 00538-31\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 31 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":53647057322250,"sku":"00538-31","price":500.0,"currency_code":"GYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00538-31_9f745c3b-12de-4257-98d5-7bcc8235e2c9.png?v=1788869623","url":"https:\/\/inter-pace.com\/en-gy\/products\/ohlins-shims-12-31-0-38-00538-31","provider":"Inter-Pace","version":"1.0","type":"link"}
