Beehive valve spring kit for Screamin' Eagle cylinder heads

FEULING® BEEHIVE® valve springs use a lighter, smaller retainer which drastically reduces valve weight, creating faster high-rev response and smoother motion compared to dual valve springs
FEULING® direct replacement endurance springs (up to 0.650" cam lift, with no need to machine or modify the rocker cover)
Eliminates valve spring separation, maximises stability and reduces valvetrain noise and vibration
BEEHIVE® FEULING® valve springs must be installed at the correct open valve height, adjusting the max. lift to the open valve height specification of the valve springs
Machined from single tapered high-tensile chrome-silicon wire, shot-peened, specially heat treated and Super NexTex finished
The kit includes FEULING® ENDURACE BEEHIVE® valve springs, heat-treated 7° lightweight titanium retainers, machined seats, seat washers, valve locks and a premium Viton® valve seal set with spring wiper system
