FEULING® ECONO performance BEEHIVE® valve springs 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. Dyno proven and track tested.

Kits include: FEULING® ECONO BEEHIVE® valve springs, lightweight 7°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.

• FEULING® 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.
• FEULING® ECONO springs allow up to 585 lift cams, no rocker box clearancing required.
• Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
• FEULING® BEEHIVE® valve springs must be installed at the correct OPEN HEIGHT, matching max lift to the open height spec of the valve springs
