Preload adjusters carry the full spring force and are built accordingly. The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable. Thread size identifies where it belongs on the unit.\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. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. 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. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\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 21933-02. dimension a 1.5 mm, dimension b 56.5 mm, dimension c 30 mm is what distinguishes this number from its neighbours in the range. Preload adjusters carry the full spring force and are built accordingly. The needle tip is the wear part: once rounded, the first few clicks stop doing anything.\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 21933-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjustment Housings\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 1.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 56.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M51x1.5\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":53652122337546,"sku":"21933-02","price":100.78,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21933-02_3cfc000b-43c4-44b4-a55e-0c7a0796dc23.png?v=1788878101","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m51x1-5-56-5-30-21933-02","provider":"Inter-Pace","version":"1.0","type":"link"}
