The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable. Corrosion inside a tube is terminal: it cannot be honed out without changing the clearance.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21875-03. This position has no published dimension, so the part number is the only reliable identifier. Most seal kits are built around a specific head design. Öhlins machines the head so the bushing bore is concentric with the seal — otherwise the shaft wears one side.\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 21875-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\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":53652901888266,"sku":"21875-03","price":197.31,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21875-03_0b5625f9-d6e0-4ee9-83d5-60c5c2a2becc.png?v=1788880385","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-head-ttx36-21875-03","provider":"Inter-Pace","version":"1.0","type":"link"}
