Sales Literature

Outstanding ride

  • Superior ride and handling provide enhanced driver comfort and protection to vehicle loads and body
  • Non-reactive to brake and acceleration torque
  • Roll-resistant design simplifies installation and maintenance


More road time

  • Proven in arduous conditions
  • Hendrickson's torsion bar eliminates the need for a costly anti-roll bar
  • Reduces weight — Increases load, ensuring maximum profitability for the end user
  • Improves packaging


Flexibility

  • Suitable for tractor and rigid applications
  • Unique suspension geometry— Parallelogram design significantly controls suspension wind up and corresponding frame rise— Driveline angles are maintained throughout axle travel, thereby reducing suspension-induced driveline vibration and extending component life
