COMP Cams Valve Spring 1.589in Beehive

With a .750" maximum lift, these Beehive Valve Springs are recommended for high lift Solid flat tappet and hydraulic Roller cams. They were designed for high performance street and track capabilities, and are used in Harley Davidson engines. COMP Cams Beehive Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehive shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Because of the unique Beehive design, the valve train can handle more RPM and more aggressive Camshaft profiles.Part #ODIDSeat LoadOpen LoadCoil BindRate (Lbs./In.)Titanium RetainerSteel RetainerCup SeatShims261201.0951.445.6501.000155 @ 1.880377 @ 1.2801.2303707947954696, 4697, 46984754 Beehive Valve Spring: Top 1.185" OD, .731" ID
