GSC Power-Division Single Beehive Valve Spring Set w/ Titanium Retainers 2002-2014 WRX / 2004-2021 STI

GSC Power-Division Beehive Springs are the result of some of the most advanced manufacturing techniques in the industry. GSC uses an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. This provides the spring with the highest level of spring load retention while still maintaining good fatigue for the life of the spring.

The Beehive spring has been designed to be more stable than standard single or dual cylindrical springs. The smaller and lighter retainer used on the beehive valve spring allows for higher RPM and more valve control.
