Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDiameter 7 mm\u003c\/li\u003e\n\u003cli\u003eLength 34.7 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eThread M7\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05521-03\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eAt 7 mm, 34.7 mm it fits one position only; the next size up carries a different number. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Port area and shim seat geometry decide the damping curve before any adjuster is touched.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 05521-03 in the exploded view for the unit it belongs to. The published dimensions are diameter 7 mm, length 34.7 mm — measure the old part against them if you are unsure. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. 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\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 05521-03\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 34.7 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":53649225810186,"sku":"05521-03","price":6.34,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05521-03_ff20282a-786e-4a05-a547-ffc945b0d041.png?v=1788874340","url":"https:\/\/inter-pace.com\/en-sr\/products\/ohlins-shaft-jet-bleed-4-m7-34-7-05521-03","provider":"Inter-Pace","version":"1.0","type":"link"}
