GSC Power-Division Single Beehive Valve Spring Set

At some point when you have reached a certain power level, you will have to start building your heads, and many of you will opt to a higher duration camshaft to rev higher, and increase your mid-range to top-end performance. When changing camshafts you will have to upgrade your intake and exhaust valves, and you will have to upgrade to a set of upgraded valve springs.

The GSC Power-Division Single Beehive Valve Springs are made with stronger and lightweight construction to provide your valves with more stability while maintaining valve control under high-RPM use. This is a common upgrade for those of you who are building your engines that are making big power and big boost numbers, that would otherwise be limited by the factory valvetrain.

This is a complete set of valve springs that will come supplied with Grade 5 titanium retainers.
