Feuling Econo Beehive Valve Spring Kit For Harley EVO / Twin Cam / Sportster 1984-2004

Feuling Econo Beehive Valve Spring Kit For Harley 

Feuling® Econo performance Beehive® valve springs are designed to handle up to 585 lift camshafts at an economical price. These Feuling® Beehive® springs are made from the same premium stress relieved conical ovate wire as our High Load springs but are developed for economical engine budgets. They have an excellent level of fatigue life and are designed to handle the demands of performance engines with 585 and smaller lift camshafts. Beehive® valve springs use a much smaller and lighter weight retainer which drastically reduces the valve weight creating a much quicker revving and smoother motion than comparable dual valve springs. Dyno proven and track tested.

Features:

• Allow up to 585 lift cams
• No rocker box clearancing required
• Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics
• Don't get stung by inferior valve springs
• Quicker revving
• Smoother motion
• Made in the U.S.A.

Kits include valve springs, lightweight steel retainers, machined heat treated chrome moly spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with a spring loaded valve stem wiper system.
