V Force 4X Reed Valve System 

Building on the success of the VForce4R, VForce4X redefines the reed valve system with a host of improvements and a complete redesign. It features an airfoil shape at the reed tip to boost air velocity and utilizes a new reed petal resin system with carbon fiber for enhanced durability. The pre-curved reed petals ensure a tighter seal, and the extended reed stops decelerate petal tip velocity, further extending life. The redesign results in over 10% increased total airflow and a 15.6% smaller frontal area of the central wing for superior aerodynamics.

Features:

  • Advanced reed petal resin system, carbon fiber and lay-up
  • Pre-curved reed petal ensures better seal at the tip
  • Wider reed cage for maximum airflow
  • Combined reed tip area is increased by 10.5% for better airflow
  • Airfoil shape added to cage tip to increase velocity from the outer ports
  • Long reed stops added to progressively slow reed petal tip velocity for increased petal durability
  • Reduced frontal area of the central wing combined with a more aerodynamic shape
  • Replacement reeds available
  • Made in the USA
