GSC Power Division Beehive Valve Springs & Titanium Retainers for BMW M2 (G87) M3 (G80) M4 (G82) S58 Engines

The GSC Power-Division Beehive Valve Spring Kit with Ti Retainers 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.
