The GSC Power-Division Beehive Valve Spring Kit with
Ti Retainer for the BMW S58 includes 24 titanium retainers (12 Intake
and 12 Exhaust) and 24 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.
