More Info:
These are a must have for anyone pushing the limits. If you have had problems with valve float or throwing rocker arms, this is the spring set that will cure your problems for good. GSC beehive springs are 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. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.
