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 38 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 04729-03\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eInner Diameter 12 mm\u003c\/li\u003e\n\u003cli\u003eThickness 0.25 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eAt 12 mm, 38 mm, 0.25 mm it fits one position only; the next size up carries a different number. Outer diameter sets the lever the oil works against, and thickness sets the resistance. Revalving means changing the stack, not the piston — that is why shims are sold singly. The stack is the tuning: outer diameter sets where the shim bends, thickness sets how hard it resists.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Suspension is one of the few areas where the original part is genuinely the cheaper decision. The exploded drawing for your unit names the number; if you do not have it, we do. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 04729-03 in the exploded view for the unit it belongs to. Öhlins states inner diameter 12 mm, outer diameter 38 mm, thickness 0.25 mm for this number, and those figures are the deciding ones. Revalving means changing the stack, which is why Öhlins sells shims individually. Shims are reused only if they are undamaged and flat; a coned shim is finished.\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 04729-03\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 38 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":53649408786698,"sku":"04729-03","price":1.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04729-03_ef1fd150-a992-4c5f-867a-10ed2bb6f7d3.png?v=1788875337","url":"https:\/\/inter-pace.com\/en-uy\/products\/ohlins-shims-12-38-0-25-04729-03","provider":"Inter-Pace","version":"1.0","type":"link"}
