BEEHIVE SPRINGS HARLEY 1.445"

Beehive Shape Reduces Spring and Retainer Weight. Less valve train reciprocating mass in motion. More stability, higher RPM, longer life and more horsepower. Requires less spring pressure for better valve control. Provides a double weight savings, reduces the weight of the spring and allows a smaller, lighter retainer. Unique Design Increases Harmonic Resistance, Yielding Greater Spring Stability. Handles valve train stress more efficiently. Increases harmonic resistance for greater stability. Eliminates damaging harmonics. Increases high RPM horsepower and durability.
