Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Valves and needles set the adjustable part of the damping; the piston sets the rest. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design.\u003c\/p\u003e\u003ch2\u003eWhy the Original\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. We can check the number against the Öhlins exploded view before you order — just ask. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 05666-14 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins does not publish a dimension here — go by the number and the exploded view. Rebuilding a piston means keeping the shim order, because the stack is the tuning. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable.\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 05666-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Valves\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":53649252122890,"sku":"05666-14","price":37.27,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05666-14_d4190d1d-897d-48bd-8dd2-4af80617a973.png?v=1788874502","url":"https:\/\/inter-pace.com\/products\/ohlins-valve-assy-dia-1-4-bleed-4-0-05666-14","provider":"Inter-Pace","version":"1.0","type":"link"}
