Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 04891-03\u003c\/li\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eLength 26 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eDimensionally this is 46 mm, 26 mm, which is how it is told apart from the rest of the range. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Every part in this catalogue is one Öhlins fits itself during assembly and service. Send us the model and serial number of your unit and we will confirm the position before you order. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 04891-03 in the exploded view for the unit it belongs to. Öhlins states diameter 46 mm, length 26 mm for this number, and those figures are the deciding ones. A head that has been over-tightened distorts and stops sealing. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 04891-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 26 mm\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":53649084875018,"sku":"04891-03","price":193.78,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04891-03_36d367e1-d4bf-4839-b142-36aca8bdcf1e.png?v=1788873671","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-head-90-pb-46-26-04891-03","provider":"Inter-Pace","version":"1.0","type":"link"}
