The beehive valve spring shape has become the buzz lately. Some have inquired as to the benefits of a beehive spring vs the dual springs that are sold by others. While some might find that the beehive spring design is new it has been used commonly in many OE engines as well as in all of the NASCAR and F1 engines of today. Why? The beehive shape is more stable than standard single or dual cylindrical springs. With the smaller and lighter retainer used on the beehive valve spring allow for higher RPM and more valve control. So beehive valve springs, with there lighter weight retainers allow for engine’s to rev quicker and maintain a more stable valve motion than the traditional cylindrical springs of yesteryear.

Description

The GSC Power-Division Beehive Valve Spring Kit with Ti retainer for all 4G63s includes 16 titanium retainers and 16 beehive valve springs. This set can be used for EVO 1-7 & EVO 8/9 if you are looking to replace the OEM retainers. Our beehive spring is made with an ovate wire which 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.
