Valve Spring Kit - Light Racing w/ HT Steel Retainers

• Type: Valve Spring Set

The Kibblewhite Precision Light Racing Valve Spring Kit is designed for high-performance applications, providing durability and optimized spring forces. Made from premium Kobe Super-Clean Chrome Silicon Wire, these springs undergo heat treatment, stress relief, and shot peening for maximum performance and longevity. Engineered using advanced simulation software, they are optimized for cam and spring harmonics, stress, mass, and operating RPM. This kit includes beehive valve springs, titanium upper collars, and lower collars, with lightweight heat-treated steel retainers to reduce reciprocating mass while maintaining the necessary spring pressure for high-performance boosted racing engines. It delivers 80 lbs of seat pressure and 205 lbs at 0.435" lift (max). The spring kit is also designed for compatibility with OEM integrated seal/base (OE# 3610212) where applicable. Sold as a complete set for one engine.
