Description

The Feuling High Load Beehive® Valve Springs are constructed from premium, stress-relieved conical ovate wire, treated with a nitrided surface for enhanced durability and wear resistance. The shot-peened surface and Nano Peen™ polish further improve fatigue life. These springs utilize a smaller, lighter retainer, reducing valve weight and enabling quicker engine speeds and smoother valve train operation. Designed for high-lift, steep-ramped camshafts, these valve springs support up to 0.750" lift without requiring rocker box modifications. Dyno and track-tested, these valve springs deliver proven performance and reliability. This kit is a direct replacement, meaning no machining is required for installation.
