Surface finish is specified in microns, because it decides how quickly the piston band wears.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21070-03\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Öhlins machines the head so the bushing bore is concentric with the seal — otherwise the shaft wears one side. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific. The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Every part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins parts are unit-specific: a close dimension is not a substitute. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21070-03 in the exploded view for the unit it belongs to. This position has no published dimension, so the part number is the only reliable identifier. A head that has been over-tightened distorts and stops sealing. Diameter and length together identify the tube — both are specific to the damper it came from.\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 21070-03\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":53652531872010,"sku":"21070-03","price":1807000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21070-03_41336932-e0e1-494a-b59f-cf99da66b1ae.png?v=1788879465","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-cylinder-head-ttx36-21070-03","provider":"Inter-Pace","version":"1.0","type":"link"}
