The GSC Power-Division Beehive Valve Spring Kit with Ti retainer for all 4G63s includes 16 titanium retaineres and 16 beehive valve springs. This set can be used for EVO 1-7 & EVO 8/9 if you are looking to replace the OEM retainers. Our beehive spring is made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilites. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.
Beehive Spring Benefits:
Rev faster
Lighter components
More durable design
Less stress on valvetrain components
Lower spring frequency for more precise valve control
More valve control equals more aggressive cam profiles
Nano peened for faster break-in and less spring stress
