Reservoir tubes carry the gas charge and are built to the same standard as the working cylinder.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21938-01\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Head and tube are matched by thread and diameter; neither is interchangeable across units.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. The alternative to a service part is usually a new damper, which is why this catalogue exists. If you are between two sizes, send us the measurement and we will check it against the catalogue. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 21938-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Where no measurement is given, the drawing position is what identifies the part. Head and tube are matched by thread and diameter; neither is interchangeable across units. 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\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 21938-01\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":53653144830218,"sku":"21938-01","price":336000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21938-01_44492d2f-fb1b-4fd8-96e6-034f2e40f034.png?v=1788880554","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-cylinder-head-s46c1-21938-01","provider":"Inter-Pace","version":"1.0","type":"link"}
