These 24v VR6 Cam Gears Plates allow removal of the VVT (Variable Valve Timing) cam phasers. While VVT may be great for OEM camshafts, most high lift aftermarket cams are not setup for use with VVT. They are built with same performance principles as non-VVT camshafts and should be used the same way. VVT relies on oil pressure to adjust cam position, which changes with temp and rpm. It has no time to make smart changes in high hp engines.
Made for 6061 billet aluminum, these weight one half the weight of the OEM cam phasers. This dramatically reduces valvetrain rotating mass, freeing up real horsepower. The Gam Gear Plates allow 10 degree adjustment in both retard and advance. These are also a must if engine cylinder head or block has been resurfaced or headspacer is being used.
Note: Gear plates, mounting bolts, and washers are provided to set up both intake and exhaust cams.
