The new VForce4 is built on the solid foundation that has made the VForce3 a success for the last 10 years. While the VForce3 has been continually refined over the years, this is a complete redesign of the entire system. We jokingly say, "The only thing we don't change is the bolt pattern." However, this is actually quite true. All of the components that go into making a VForce tube system have been significantly modified since the VForce3.

Doubles the surface area of the reed tip over a conventional reed valve design
Increased bottom end, stronger midrange and longer top end
Greater efficiency due to the reduction of the travel of the reed petals.
More airflow means more horsepower
Reduced wear on reed petals
Boltless design eliminates the risk of bolts going through the cane engine.
Screwless design allows for super-fast reed petal changes

New and Improved VFORCE4 Features
Resin reed system, carbon fiber and stacking.
Pre-curved reed petal ensures a better seal at the tip
Wider rod cage for maximum airflow
Combined reed tip area a increased by 10.5%, resulting in greater overall airflow
Aerodynamic shaping added to the tip of the cage to increase air velocity from the outer ports
Added Added long stops to progressively slow the petal tip, for greater petal durability
Reduction of the frontal area of the central wing by 15.6% combined with a more shape aerodynamics.

Includes: installation instructions, complete VForce4 valve system (including two reed valves with reed petals), and gaskets.
