These springs are engineered to withstand the rigors of high-performance engines, ensuring reliable valve control and enhanced engine performance. Experience the benefits of reduced valve weight, quicker revving, and smoother engine operation.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Feuling High Load Beehive® Valve Springs are designed for demanding performance engines with high-lift, steep-ramped camshafts, allowing up to 0.750\" lift cams. These springs are manufactured from premium stress-relieved conical ovate wire, treated with a nitrided surface heat treatment, and enhanced with shot-peened surface and Nano Peen™ polish. This meticulous construction provides an extremely high level of fatigue life, proven through dyno and track testing. The kit is a direct replacement, requiring no machining or rocker box clearance for most applications. However, larger camshafts may require valve guide machining for seal-to-retainer clearance. This kit ensures optimal valve train performance and reliability for your high-performance engine, maximizing power and responsiveness.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eCrafted from premium stress-relieved conical ovate wire for superior durability.\u003c\/li\u003e\n    \u003cli\u003eNitrided surface heat treatment, shot-peened surface enhancements, and Nano Peen™ polish maximize fatigue life.\u003c\/li\u003e\n    \u003cli\u003eLightweight 10° Titanium retainers (Ti-17 alloy) reduce valve weight for quicker revving and smoother motion.\u003c\/li\u003e\n    \u003cli\u003eDesigned for high-performance engines with high-lift, steep-ramped camshafts, allowing up to 0.750\" lift cams.\u003c\/li\u003e\n    \u003cli\u003eDirect replacement, no machining or rocker box clearance required for many applications.\u003c\/li\u003e\n    \u003cli\u003eDyno proven and track tested for reliability and performance.\u003c\/li\u003e\n    \u003cli\u003eMade in the USA.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eBrand: Feuling Parts\u003c\/li\u003e\n    \u003cli\u003eProduct Name: Spring Kit\u003c\/li\u003e\n    \u003cli\u003eType: Valve Spring Kit\u003c\/li\u003e\n    \u003cli\u003eApplication: Exhaust, Intake\u003c\/li\u003e\n    \u003cli\u003eSpring Lift: 0.750\"\u003c\/li\u003e\n    \u003cli\u003eCollar Material: Titanium\u003c\/li\u003e\n    \u003cli\u003eMaterial: Steel\u003c\/li\u003e\n    \u003cli\u003eSeat Load at 1.935\" Installed Height: 170 lb (0.720\" lift)\u003c\/li\u003e\n    \u003cli\u003eSeat Load at 1.900\" Installed Height: 185 lb (0.685\" lift)\u003c\/li\u003e\n    \u003cli\u003eSeat Load at 1.845\" Installed Height: 200 lb (0.630\" lift)\u003c\/li\u003e\n    \u003cli\u003eSeat Load at 1.819\" Installed Height: 208 lb (0.604\" lift)\u003c\/li\u003e\n    \u003cli\u003eSeat Load at 1.800\" Installed Height: 215 lb (0.585\" lift)\u003c\/li\u003e\n    \u003cli\u003eSeat Load at 1.789\" Installed Height: 217 lb (0.574\" lift)\u003c\/li\u003e\n    \u003cli\u003eOpen Load at 1.215\" Open Height: 415 lb\u003c\/li\u003e\n    \u003cli\u003eCoil Bind: 1.125\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eValve springs must be installed at the correct OPEN HEIGHT, matching max lift to the open height spec of the valve springs.\u003c\/li\u003e\n    \u003cli\u003eUp to 0.574\" lift for '84-'04 Big Twin and '86-'03 XL.\u003c\/li\u003e\n    \u003cli\u003eUp to 0.700\" lift for '05-'17 Twin Cam.\u003c\/li\u003e\n    \u003cli\u003eLarger camshafts may require valve guide machining for seal-to-retainer clearance.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Feuling Parts","offers":[{"title":"Default Title","offer_id":53653572583754,"sku":"09260853","price":507.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/f692bb84e2a8b20f34625506ea94018f.webp?v=1766576604","url":"https:\/\/partsdenmark.com\/products\/feuling-high-load-beehive-valve-springs-750","provider":"Parts Denmark","version":"1.0","type":"link"}
