Patented dual-stage design incorporates a specially shaped top reed and ported bottom reed
Top reed is lightweight and resilient for crisp throttle response at low-mid rpm's
Stiffer bottom reed is ported to provide maximum flow and horsepower at higher rpm's
The dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently
The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports
Dual-stage reeds work in unison to perform efficiently throughout the entire powerband
The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure
Quicker acceleration, crisper throttle response and increased horsepower throughout the powerband
