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.

The GSC Power-Division billet 7008S2 cams for the Mitsubishi Evo 4-8 are designed for those with a goal of 400-700 WHP. No low end power is lost vs. the stock cams when used with the larger turbos. The S2 cams will show gains of 50-70 WHP over the stock cams, and in some cases more in the higher RPMs. Great for 2.0L engines with stock frame turbos revving to 9000 RPMs or for stroker motors revving to 8000 RPMs. 

**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**
