Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact. Piston bands are consumables — they wear against the bore and lose their seal gradually. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. Öhlins parts are unit-specific: a close dimension is not a substitute. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 04773-05. Where several sizes share a description, only the number separates them. Öhlins does not publish a dimension here — go by the number and the exploded view. Jets meter fixed bleed flow and are sized in tenths of a millimetre. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 04773-05\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Piston Holders\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":53649063248138,"sku":"04773-05","price":87.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04773-05_1fe7f33f-402a-40f1-a98b-1298997635a0.png?v=1788873516","url":"https:\/\/inter-pace.com\/en-bh\/products\/ohlins-piston-holder-b-04773-05","provider":"Inter-Pace","version":"1.0","type":"link"}
