The GSC Power-Division Beehive Valve Spring Kit with Ti retainer for all 4G63s includes 16 titanium retainers 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 utilizes advanced material heat treatment methods for superior load loss capabilities. 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.
