Too stiff and the front loses feel over bumps; too soft and it dives under the brakes. Rate sets that balance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003cli\u003eFree length 423 mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 38.2 mm\u003c\/li\u003e\n\u003cli\u003e280 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 08789-38\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 3.8 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eShafts are hardened and surface-treated so the seal has a consistent surface to run against. The finish is applied after setting, which means the coating does not affect the rate. Öhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eAt 423 mm free length and 38.2 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.\u003c\/p\u003e\u003ch2\u003eChoosing 3.8 N\/mm\u003c\/h2\u003e\u003cp\u003eSoft rates like this are what off-road and adventure forks need: the wheel has to follow the ground, not deflect off it. A rate this low belongs on a long-travel machine or under a light rider — it lets the fork use its full stroke instead of riding high and skating over the surface. A very soft rate uses more of the stroke, which is usually what an off-road chassis wants. A road machine spends most of its life in the first third of the fork's travel — that is the part the rate governs.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eÖhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eThe fork legs come off, the springs are swapped and the oil level is reset — half a day in most workshops. Both legs are done together, and both take the same rate. Note the original oil level before draining — it is a useful reference even when Öhlins specifies its own.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: not applicable to the spring on its own. Öhlins issues approvals against complete suspension units, not individual springs.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins suspension rewards careful fitting. We recommend having the work done by an authorised Öhlins service centre — and we are one ourselves: we fit, service and set up Öhlins components in house. If you would like us to handle the installation, just ask and we will quote it with the order.\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 08789-38\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 3.8 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 423 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 38.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 280 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eConstruction:\u003c\/em\u003e Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePackaging Unit:\u003c\/em\u003e Pair\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":53645393559818,"sku":"08789-38","price":161.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/ForkSprings-v2_a0fc2cbf-3caf-4c4b-9751-53fb5834e8f4.png?v=1788864295","url":"https:\/\/inter-pace.com\/en-nl\/products\/ohlins-fork-springs-3-8-n-mm-423-mm-38-2-mm-08789-38","provider":"Inter-Pace","version":"1.0","type":"link"}
