Valves and needles set the adjustable part of the damping; the piston sets the rest. Rebuilding a piston means keeping the shim order, because the stack is the tuning. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Order by part number — descriptions repeat across sizes, numbers do not. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 05621-02 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. diameter 7 mm, length 37.7 mm is what distinguishes this number from its neighbours in the range. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. 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\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 05621-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Jets\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 7 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 37.7 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M7\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":53649236787466,"sku":"05621-02","price":17.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05621-02_1acb1c76-2372-4402-be26-ae53bbff4904.png?v=1788874404","url":"https:\/\/inter-pace.com\/en-mc\/products\/ohlins-shaft-jet-bleed-2-5-m7-37-7-05621-02","provider":"Inter-Pace","version":"1.0","type":"link"}
