MMR / Manley 2007-2014 GT500 / Ford GT Valve Spring kit

MMR/Manley GT500 / Ford GT Cylinder Valve Spring kit

This kit contains the Springs and Titanium retainers for the Shelby GT500 & Ford GT Supercar Cylinder heads. Standard 4V springs from Comp cams and Manley will not work with these heads due to the separate installed heights on the intake and exhaust. This kit has been properly engineered to maintain the correct installed heights and work with stock and ALL aftermarket cams. The increased seat pressure that this kit produces is also great for High boost applications.
