This spring will last 2 to 3 times longer and give you 10 additional pounds of seat & 25 more pounds open pressure. They look and install exactly like the springs for the GM Crate engines.  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. CTS have 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.

They are Cryogenic treated for extra-long life.

Especially Designed Coil Material with our “Variable Rate” that allows More RPM Capability and Much Better Endurance (i.e. All Season Long).
