JDM Super Stock  2007-2014 Shelby GT500 Camshaft Upgrade

Get your GT500 idle chopping like an old school muscle car of the 60's and breathing better too with JDM’s Super Stock Camshaft kit.  These NHRA Super Stock legal cams were born on the drag strip for winning races and breaking records, but are right at home in your 2007-2014 GT500 for making big power gains without sacrificing drivability.  Depending on application, we have seen up to 100 horsepower gained from installing our camshafts, while gaining another 500 RPM in the rev range.  We find these cams ideal for those looking to free up some power with a bigger blower.

Included in the JDM Super Stock Camshaft kit is a set of High Pressure Valve Springs which will stabilize the valve-train and prevent valve float. Our revised PAC valve springs are a direct fit with stock retainers but Chromoly steel or Titanium retainers are available for High Performance and or Racing applications for added durability.  These camshafts require a tune which we can facilitate depending on application,. Please give us a call for details. 

**NOTE! We HIGHLY recommend verifying installed height, along with degreeing the cams on install.  This job should be attempted by a trained technician.  Contact JDM Engineering Technical Department with further questions or information in regards to install.**

*** Requires new camshaft bolts as stock bolts are torque to yield*** Choose at check out our bolt option (OEM + $40.00 or ARP-256-1001+ $92.00)
