Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. We can check the number against the Öhlins exploded view before you order — just ask.\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 06798-21. Where no measurement is given, the drawing position is what identifies the part. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 06798-21\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Strut Casings\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":53652073382154,"sku":"06798-21","price":1474.14,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/06798-21_c5057d91-19e6-43ed-8d87-5968a3e51f2d.png?v=1788878043","url":"https:\/\/inter-pace.com\/en-ca\/products\/ohlins-strut-casing-tpx44-left-l300-06798-21","provider":"Inter-Pace","version":"1.0","type":"link"}
