Then you are experiencing valve float and reversion. Stock springs rated at just 80 lbs 0f seat pressure (at 1.380″) can’t consistently control the valvetrain under high boost or high rpm. As boost pressure increases, the valves risk being blown open, causing reversion—the reintroduction of exhaust gases into the cylinder on the intake stroke. Excessive exhaust gasses greatly slow combustion and reduce power. As rpm goes above 3800 rpm, the OEM springs do not have enough pressure to stop valve float, which can cause cast tappets to fracture.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncreased Seat Pressure: Eliminate the risk of valves blowing open under high boost\/rpm.\u003c\/li\u003e\n\u003cli\u003eOptimized Power Delivery: Prevent reversion for cleaner, more efficient combustion.\u003c\/li\u003e\n\u003cli\u003eProtect Your Camshaft: higher seat pressure, but moderate nose pressure, gives you the pressure you need to control your valvetrain to 4500rpm without the worry of cam or tappet failure.\u003c\/li\u003e\n\u003cli\u003eReliable Performance to 4,500 RPM: Beyond 4,500 RPM, consider upgrading to our #110 springs for safer operation.\u003c\/li\u003e\n\u003cli\u003eWarranty Considerations: We only warranty our cams if you run Hamilton springs and tappets—protect your investment from avoidable wear and damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Insights\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNote: Tool steel retainers are not included but can be purchased separately.\u003c\/p\u003e\n\u003cp\u003eStep up to Hamilton 24V Valve Springs and keep your valvetrain under control in high-boost, high-RPM conditions—so you can maximize power, protect your cam, and drive with confidence.\u003c\/p\u003e","brand":"Hamilton Cams","offers":[{"title":"Default Title","offer_id":43362760720635,"sku":"07-S-003","price":561.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0576\/3298\/1184\/products\/1998-5-2018-cummins-5-9l6-7l-hamilton-cams-valve-spring-set-07-s-003-hamilton-cams.png?v=1725581992"},{"product_id":"1998-5-2018-dodge-cummins-24v-spring-and-retainer-set-fpe-34797","title":"1998.5-2018 Cummins 5.9L\/6.7L Spring and Retainer Set (FPE-34797)","description":"\u003cp\u003eUpgrade your Cummins valve springs and retainers with our Fleece Performance spring and retainer kit.
