Head diameter and thread are specific to the tube it closes. Öhlins builds the head so the dust seal takes the grit before it reaches the oil seal. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eAn original part keeps the unit within its published specification; a near-equivalent quietly moves it. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. We can supply the whole position from the drawing rather than the single piece if that is easier. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21647-02 is the Öhlins number for this position — the same one printed in the service documentation. Where no measurement is given, the drawing position is what identifies the part. Assembly grease matters — the wrong compound swells the seal and it fails early. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.\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 21647-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal 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":53650857689354,"sku":"21647-02","price":48.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21647-02_c3df5d57-e879-4d67-86d6-8aeee2fbe4c2.png?v=1788877413","url":"https:\/\/inter-pace.com\/en-mg\/products\/ohlins-seal-head-front-fork-36-5-21647-02","provider":"Inter-Pace","version":"1.0","type":"link"}
