Ferrea Valve Spring Kit
Help improve the valve train of your Ecotec powered Cobalt, Cobalt SS/SC, Cavalier/Sunfire, Saturn Redline, HHR or even your Off Road Buggy with these PROVEN dual coil valve springs. The springs will prevent floating valves in the upper RPM range and will allow for higher lift cams without coil binding.
Includes Dual Coil Spring, Spring retainers, and optional valve spring seat locators.
