Single Outer Valve Springs from COMP Cams allow you to build the perfect spring assembly for your application. The valve spring creation process is far more involved than most people realize. Selecting the right metal stock and creating the best design is not done by chance. COMP Cams has developed a process that creates the highest quality valve spring available. The result is a product that meets and exceeds the expectations of today’s engine builders and racers.

Product Features:

• Seat pressure: 115 lbs. @ 1.700″, Open Pressure: 284 lbs. @ 1.200″
• O.D.: 1.437″, I.D.: 1.039″
• Single valve springs with damper
• Approximately .510″ max lift at recommended installed height

This Beehive Valve Spring Kit for LS engines is designed for hydraulic roller cams and includes carefully matched Beehive Springs, steel retainers, locks, seals and spring seats. With a .625″ maximum lift, these 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.Kit Includes:26918-16 Beehive Valve Springs774-16 Steel Retainers623-16 7° Steel Valve Locks511-16 Valve Seals4705-16 Spring Seats
