Needle geometry sets the shape of the adjustable range, not just its size. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Rebuilding a piston means keeping the shim order, because the stack is the tuning.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Order by part number — descriptions repeat across sizes, numbers do not. If the unit is already apart, compare the published dimensions with the part in your hand.\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 — 00405-01 in this case. Where no measurement is given, the drawing position is what identifies the part. Piston bands are consumables — they wear against the bore and lose their seal gradually. Rebuilding a piston means keeping the shim order, because the stack is the tuning.\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 00405-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\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":53648777543946,"sku":"00405-01","price":100.0,"currency_code":"GTQ","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00405-01_825b703a-b751-492d-bf49-dd318966a464.png?v=1788871836","url":"https:\/\/inter-pace.com\/en-gt\/products\/ohlins-reservoir-piston-49-00405-01","provider":"Inter-Pace","version":"1.0","type":"link"}
