The GSC Power-Division Beehive Valve Spring Kit for the EVO 8/9 includes 16 beehive valve springs only. These are a replacement for the factory beehive springs and will work with the factory seat and retainer for an easy and inexpensive upgrade. Our beehive spring is made with an ovate wire which 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.GSC Power-Division Beehive spring set for EVO 8/9 only
