Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.\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 21813-15\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThere is no measurement to check here — the number and the exploded view identify it. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range. A preload adjuster carries the full spring load and is built as a structural part. A rounded tip means the first clicks stop doing anything.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. If the unit is already apart, compare the published dimensions with the part in your hand. 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\u003e21813-15 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. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function. Click adjusters work through a needle in a seat; the detent spring gives the clicks their feel.\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 21813-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjustment Needles\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":53652871020810,"sku":"21813-15","price":8.39,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21813-15_b4dedd68-c05a-4e32-8bce-e622f6bdd8ab.png?v=1788880290","url":"https:\/\/inter-pace.com\/products\/ohlins-needle-15deg-18-5-21813-15","provider":"Inter-Pace","version":"1.0","type":"link"}
