This complete kit includes thermally treated, machined, and hand-labelled oval chromoly wire springs according to their winding and the required lift height. Designed to reduce the moving mass of the valvetrain, it facilitates smoother valve movement at high RPM.
- Kit contents: Econo BeeHive® springs, lightweight retainers (steel or titanium 7°), machined and treated chromoly spring seats, spacers, keys, and premium Viton® valve stem seals with spring-loaded valve guide.
