Suspension Systems > AIRTEK NXT


Integrated Front Air Suspension and Steer Axle System

AIRTEK’s superior design and engineering improves roll stability versus standard suspensions. Its exclusive air springs support a majority of the load, greatly increasing driver comfort. Premium rubber bushings are incorporated to aid in the isolation of noise, vibration and harshness, which helps protect valuable cab components and contributes to AIRTEK’s exceptional ride quality. AIRTEK assists in protecting drivers
from bumps and potholes, providing a premium ride while maintaining constant ride height.

The AIRTEK suspension, combined with Hendrickson’s STEERTEK NXT fabricated axle, is up to 44Kg lighter than traditional forged axle and steel springs designed to improve load capacity and help enhance fuel efficiency.
