Ford 4.6/5.4L 3 valve adjustable cam gear set.

Ford 4.6/5.4L 3 valve adjustable cam gear set. Not all aftermarket camshafts are compatible with the factory variable cam timing feature. These gears allow you to lock in the cam centerline where you need it. Gear sets can also allow you to swap a 3 valve engine in place of your 2 valve engine. The single pole reluctor can be installed on your LH gear to allow the use of your 2 valve electronics.

Price: $399.99

The gear on the left side  works with the two valve computer.  The gear on the right side works with the '05 up Mustangs with the stock 3V computer. The same gear would be used on both sides and the variable cam timing function will be disabled.
