Overview of Progressive Suspension Black Standard 440 Series Shocks - 115/155 Spring Rate (lbs/in) - 440-4054B

  • The Inertia Active System (I.A.S.) 440 Series Twin Shocks are the most state-of-the-art shocks available to the public
  • The 440 Series Shock is able to separate chassis movement from wheel movement
  • This shock is able to float over the rough stuff, yet won't wallow in the twists and turns
  • The best shock today for high torque shaft drives, no other shock can control the torque inputs of a shaft drive and still maintain a smooth, plush ride
  • Powder coated damper and Black Nitride shaft
  • High pressure gas charged for fade-free operation
  • Two independent rebound damping circuits
  • Inertia valve determines whether the soft (wheel) circuit or the firm (chassis) circuit is utilized to optimize both the handling and comfort automatically
  • All three damping circuits, compression as well as soft and firm rebound, are also velocity sensitive
  • Limited lifetime warranty
