Description

The 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.
