Piston bands are consumables — they wear against the bore and lose their seal gradually. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Rebuilding to specification only works if the parts are to specification — that starts here. Öhlins parts are unit-specific: a close dimension is not a substitute. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 00305-03 in the exploded view for the unit it belongs to. Öhlins does not publish a dimension here — go by the number and the exploded view. The piston carries the shim stacks and meters the oil through its ports. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design.\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 00305-03\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":53648721412362,"sku":"00305-03","price":23.75,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00305-03_5d988e6a-c278-48a8-996f-6a67610a56ba.png?v=1788871609","url":"https:\/\/inter-pace.com\/en-ht\/products\/ohlins-reservoir-piston-36-00305-03","provider":"Inter-Pace","version":"1.0","type":"link"}
