GSC Beehive Spring Set with Titanium Retainer for all 4G63s (5041)

The GSC Power-Division Beehive Valve Spring Kit with Ti retainer for all 4G63s includes 16 titanium retainers and 16 beehive valve springs. This kit is capable of 10,500 RPM with as much as 12.1mm lift cams (net valve lift max due to seal to bottom retainer contact). These are a must have for anyone pushing the limits. If you have had problems with valve float or throwing rocker arms, this is the spring set that will cure your problems for good. 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.
