2007-2014 GT500 Valve spring kits by MMR
We have been getting alot of calls lately for our valve spring and retainer kit for the Ford GT/GT 500 heads. It seems alot of people were not aware we had this kit so we figured we would post some info for those looking to upgrade springs or add cams.
The kit allows use of any 4v camshafts up to .550 lift (all durations except solid roller cams((non hydraulic)) -open and closed pressures available upon request
The Kit includes Gt 500/Ford GT specific intake and exhaust beehive springs manufactured for us by Manley along with custom MMR/Manley Titanium spring retainers. These kits require no machine work or modification and work with the factory valves.
These kits are also great for High boost applications to prevent the intake valve from opening from excessive pressure on the back side. This kit is used by team MMR, Shelby America, Tasca Ford and Manly others! WARNING- STD 4V SPRINGS FROM MANLEY OR COMP CAMS DO NOT WORK IN GT500 /FORD GT HEADS
