COMFORT AIR® - Hendrickson
An engineered ride solution designed specifically for ambulances. This suspension offers superior ride and handling for passenger comfort as well as vehicle protection.
  • The main support members extended-length generates lower spring rate for optimized roll stiffness providing a more comfortable and compliant ride. To further soften the ride, a longer main support member allows the air springs to carry more of the vertical load.
  • The wide footprint of the hanger distributes load over a larger area for reduced frame stress
  • The axle center is on a horizontal line with the pivot point, providing neutral roll steer for better handling
  • Durable pivot bushing connection provides quiet operation and helps extend suspension service life
  • Hendrickson’s proven QUIK-ALIGN® axle alignment feature allows fast and easy alignment without shims
  • Shocks are tuned for optimum damping characteristics to provide maximum driving comfort
  • Ambulance version offers the same features and benefits as above plus:
    • Increase axle travel to permit vehicle lowering or kneeling for easy gurney transfer
    • Transverse rod with spherical joints to provide resistance-free axle travel for full kneeling capability
    • Optional pressure check valve to decrease the time required to air up from a kneeling position to the ride height
