VALC Valve Lift Profile Velocity, Acceleration, Lift, Control
The new VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' which in turn generates more power. (Greater area under the 'lift curve' = increased air intake.)


VALC Features:
- Optimized 'Velocity' and 'Acceleration'
- Designed for High Power Setups
- Optimizes Engine Performance
- Higher Lift Than Other Profiles of The Duration
- Reduced Stess/Wear on the Valvetrain
Fits:
