Upgrade valve control and reduce reciprocating mass with the Econo Beehive® Valve Spring Kit 🔧.

Made from heat treated chromoly conical ovate wire, each spring is hand measured and labeled to the required open height to ensure consistent performance.

The kit uses much smaller, lighter retainers to reduce valve weight for quicker revs and smoother motion, and is dyno proven and track tested.

Kit includes lightweight 7° steel or titanium retainers, machined heat-treated chromoly spring seats, seat shims, valve locks and premium Viton® valve seals with a spring-loaded valve stem wiper system.

Designed for up to 0.585" lift; direct replacement with no machining or rocker box clearance required for cams up to 0.574" for '84-'04 Big Twin and '86-'03 XL, and up to 0.585" for '05-'17 Twin Cam.

Made in the USA. Feuling® BeeHive® valve springs must be installed at the correct open height to match the cam's maximum lift.
