GSC Power Division Evo X Beehive Spring set w/ Titanium Retainer 4B11T includes 16 titanium retainers and 16 beehive valve springs. 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.
