GSC Power-Division Beehive Spring Kit w/ Titanium Retainers | 2008-2015 Mitsubishi Evo X 4B11T

Beehive Valve Springs with Titanium Retainers by GSC Power-Division

The GSC Power-Division Beehive Spring Kit with Titanium Retainers for the Mitsubishi 4B11T includes 16 titanium retainers and 16 beehive valve springs. Our beehive spring is made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilites. 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. This is a must have for anyone pushing the limits.
