Description

• Product

• • 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® endurance springs are a direct bolt-in replacement (Up to 650 cam lift and doesn’t require machining or rocker box clearancing)
  • Eliminates valve spring separation, maximizes stability, reduces valve-train noise and 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
  • Machined from a premium grade Hi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processed thermal heat treatment and super NexTex finish
  • Kit includes FEULING® ENDURACE BEEHIVE® valve springs, lightweight 7° Titanium heat treated retainers, machined spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with a spring loaded valve stem wiper system
