We specialize in engineering engine components optimized for high performance engines with the highest quality and attention to detail possible. Our ultra racing valve spring kits are designed to maintain precise valve control, even in the most extreme conditions. By manufacturing our springs with chamfered ends from the highest quality chrome silicone steel and putting them through a two step heat treatment and stress relief process, we ensure precision and dependability.
Included with this kit are valve springs, lightweight titanium retainers and hardened steel spring seats.
