Engineered for extreme durability and optimal performance, this kit ensures your valvetrain can handle the demands of high-performance riding and large lift camshafts.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Feuling High Load Beehive Valve Spring Kit is meticulously machined from a premium grade Hi-tensile chrome silicon single conical ovate wire, designed to withstand the most demanding V-Twin engine applications. Each spring undergoes a rigorous shot-peening process, combined with a specially processed thermal heat treat and a super NexTex® finish. This advanced treatment significantly enhances fatigue life, ensuring your engine performs reliably from stock configurations to high-performance setups.\u003c\/p\u003e\n\u003cp\u003eFeuling's innovative Beehive design incorporates smaller, lighter weight retainers, which drastically reduce overall valve weight. This critical reduction promotes quicker engine revving and smoother valvetrain motion compared to traditional dual or single valve springs. The kit is engineered to eliminate valve spring separation, maximize stability, and effectively reduce valvetrain noise and harmonics, contributing to a more efficient and durable engine. These valve springs offer a direct bolt-in replacement for lifts up to 0.565\", requiring no spring seat or rocker cover machining. While they can accommodate over 0.600\" cam lift, this will necessitate spring seat pocket machining on the cylinder heads to achieve the correct open height. Designed to fit factory-style 6.00 mm valve stems with a triple groove, this kit is recommended for +0.540” lift camshafts and race-style engines.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Material \u0026amp; Finish:\u003c\/strong\u003e Machined from premium Hi-tensile chrome silicon ovate wire, shot-peened, thermal heat treated, and finished with NexTex® for superior fatigue life in V-Twin engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Beehive Design:\u003c\/strong\u003e Features smaller, lighter retainers that drastically reduce valve weight, promoting quicker engine revving and smoother valvetrain operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Valvetrain Stability:\u003c\/strong\u003e Engineered to eliminate valve spring separation, maximize stability, and significantly reduce valvetrain noise and harmonics for improved engine reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Lift Compatibility:\u003c\/strong\u003e Provides a direct bolt-in solution for cam lifts up to 0.565\" without machining, and can accommodate over 0.600\" lift with minor cylinder head modifications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive Kit:\u003c\/strong\u003e Includes a matched set of Feuling® High Load Beehive® valve springs, Ti retainers, machined spring seats, seat shims, valve locks, and premium Viton® valve seals with a spring-loaded valve stem wiper system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Fitment:\u003c\/strong\u003e Designed for precise compatibility with factory-style 6.00 mm valve stems and triple groove setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Proudly manufactured in the USA, ensuring high-quality craftsmanship and materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Valve Spring Kit\u003c\/li\u003e\n\u003cli\u003eModel: High-Load Beehive\u003c\/li\u003e\n\u003cli\u003eStyle: Ovate Wire Beehive\u003c\/li\u003e\n\u003cli\u003eMaterial: Hi-tensile Chrome Silicon\u003c\/li\u003e\n\u003cli\u003eFinish: Shot-peened, Thermal Heat Treat, NexTex®\u003c\/li\u003e\n\u003cli\u003eValve Stem Compatibility: Factory style 6.00 mm, Triple Groove\u003c\/li\u003e\n\u003cli\u003eInstalled Height \/ Seat Pressure:\n    \u003cul\u003e\n        \u003cli\u003e151 lb @ 1.475\" (0.485\" Lift)\u003c\/li\u003e\n        \u003cli\u003e144 lb @ 1.498\" (0.508\" Lift)\u003c\/li\u003e\n        \u003cli\u003e143 lb @ 1.501\" (0.511\" Lift)\u003c\/li\u003e\n        \u003cli\u003e140 lb @ 1.511\" (0.521\" Lift)\u003c\/li\u003e\n        \u003cli\u003e124 lb @ 1.562\" (0.578\" Lift)\u003c\/li\u003e\n        \u003cli\u003e120 lb @ 1.582\" (0.592\" Lift)\u003c\/li\u003e\n    \u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOpen Height: 304 lb @ 0.990\"\u003c\/li\u003e\n\u003cli\u003eCoil Bind: 0.945\"\u003c\/li\u003e\n\u003cli\u003eMaximum Lift (Direct Bolt-in): 0.565\"\u003c\/li\u003e\n\u003cli\u003eMaximum Lift (with machining): Over 0.600\"\u003c\/li\u003e\n\u003cli\u003eRecommended Camshaft Lift: +0.540”\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eImportant to Know\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFor cam lifts over 0.600\", spring seat pocket machining on the cylinder heads is required to achieve the correct spring open height.\u003c\/li\u003e\n\u003cli\u003eFeuling® BeeHive® valve springs must be installed at the correct open height, matching the maximum lift to the open height specification of the valve springs.\u003c\/li\u003e\n\u003cli\u003eThis kit is only recommended for large lift camshafts and race-style engines.
