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.

“With a .625″” maximum lift, these Beehive Valve Springs were designed for hydraulic roller cams in LS1, LS2 and LS6 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 cam profiles.”

Edelbrock part No: 9738 Performer-Plus lifter set for S/B & B/B Chevy is designed for use with Edelbrock Performer-Plus or equivalent camshafts. Sold in complete sets.

COMP Cams Hydraulic Roller Lifters are a performance upgrade for stock hydraulic roller lifters or retro-fit hydraulic roller lifters for non-roller blocks. The roller wheel decreases friction and increases longevity when compared to flat tappet lifters. Hydraulic roller lifters can handle much more aggressive cam profiles than flat tappets unlocking performance potential.

HYDRAULIC ROLLER – Xtreme Energy Retro-Fit: Street/strip applications, works well in large c.i. street machine with 2500+ stall.

HYDRAULIC – Xtreme Energy: Strong torque. Excellent response, heavy towing in 454 with 4.10 gear.

Featuring a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing driveability and creature comforts, the Xtreme Energy grind family offers gains in torque and horsepower while still delivering adequate vacuum for power brakes and other vacuum dependent accessories. Xtreme Energy camshafts work great in carbureted applications, but offer the best performance with aftermarket intake manifolds, lower gear ratios, headers and free flowing exhaust.
