{"product_id":"ohlins-housing-left-21509-04","title":"Öhlins Housing left – 21509-04","description":"\u003cp\u003eHousing left, Öhlins part number 21509-04. A housing carries adjusters and their seals, so its bores matter as much as its outside.\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 21509-04\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 machines housings from solid billet rather than casting them. Clamps have a specified torque; over-tightening distorts the bore they hold. Brackets locate the damper or reservoir against the chassis and take the load in one direction only.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Rebuilding to specification only works if the parts are to specification — that starts here. Tell us the damper's model designation and year and we will match the number for you. Service parts are supplied per piece unless the description says otherwise.\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 21509-04. Öhlins does not publish a dimension here — go by the number and the exploded view. Öhlins anodises housings for corrosion resistance rather than for looks. Öhlins machines its housings from solid rather than casting them, which keeps the bores true.\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 21509-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Housings\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":53652567851274,"sku":"21509-04","price":204.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21509-04_135260b2-d360-4e3e-a7b5-217377e06a7c.png?v=1788879585","url":"https:\/\/inter-pace.com\/products\/ohlins-housing-left-21509-04","provider":"Inter-Pace","version":"1.0","type":"link"}
