The GSC Power-Division Beehive Valve Spring Kit with Titanium Retainers for the Toyota/BMW B58 includes 24 titanium retainers (12 Intake and 12 Exhaust) and 24 beehive valve springs. GSC beehive springs utilise advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while maintaining good fatigue throughout the life of the spring. Beehive springs allow for a smaller, lighter retainer allowing for higher RPM and more valve control.
