Description

The Kibblewhite Beehive Valve Spring Kit delivers superior valve spring performance, crucial for maintaining consistent valve control at high RPMs. These springs are progressively wound using Kobe super-clean, chromium silicon (CrSi) based wire. Each spring undergoes heat treatment and shot peening, increasing its durability and resistance to fatigue. The kit features tight-tolerance, FEA-designed hardened steel Posi-Loc™ style upper or titanium retainers, ensuring the correct assembly height and preventing keeper "pull through." Heat treated (H.T.) steel basewashers are included to fit seamlessly on top of either the OEM or KPMI tophat seals. Optimize your engine's potential with this high-quality valve spring kit.
