INTRAAX® AANT

Narrow-Bushing, Tapered-Beam Top-Mount Air Suspension/Axle/Brake System

INTRAAX AANT  Top-Mount Air Suspension/Axle/Brake System

The ultimate system for weight-conscious haulers running straight-frame platforms, container chassis, liquid tankers, grain hoppers, bottom dumps and livestock trailers. The INTRAAX AANT 23K boasts a capacity of 23,000 pounds in ride heights from 12 to 19 inches. The tapered beam design allowed us to trim more than 35 pounds from the suspension while still maintaining the smooth ride, superior performance and rugged durability you have come to expect from INTRAAX.

Hendrickson's exclusive ZMD® ZERO MAINTENANCE DAMPING® ride technology is available as an option on select models.

Hendrickson recommends reviewing our application guide when choosing the suspension that best meets your needs.
