Driver Comfort

• Air springs support the majority of the vehicle load while providing low spring rate and extremely soft ride.
• Premium shock absorbers are tuned specifically for AIRTEK.

Stability and Handling

• Integrated design allows optimized steering geometry for reduced bump steer and wheel kick.
• The rigid front leaf spring attaches securely to the box section axle, forming a torsion system for enhanced roll stability.
• AIRTEK and STEERTEK NXT deliver up to 50° wheel cut for improved maneuverability.
• Height control valve maintains constant ride height.

Lightweight

• AIRTEK offers up to 97 lbs. of weight savings when compared to a traditional forged axle and steel spring.

Maintenance and Durability

• Premium kingpin bushings and seals provide enhanced protection from the elements to improve bushing life.
• Maintenance-free bushings and the two-piece knuckle reduce overall system maintenance.
• Air springs reduce vibration to cab, chassis, and engine components.
• Available OEM unitized hubs for extended wheel bearing life.

Brake Compatibility

• Compatible with drum or disc brakes.
• Accepts both 5/8" and 3/4" brake hardware.

AIRTEK is approved for on-highway usage with up to 15 percent operation on unpaved secondary roads. Other applications must be pre-approved by both Hendrickson and vehicle manufacturer. AIRTEK is integral to and available exclusively with the STEERTEK NXT axle. STEERTEK NXT fabricated axles can be used in applications that are up to 100 percent off road. Contact Hendrickson for approval and guidelines on any application that exceeds 10 percent off road usage. This system is anti-lock braking system (ABS) ready. STEERTEK NXT is compatible with industry standard wheel ends and brakes. Unitized hubs are available. STEERTEK NXT is also available with mechanical suspension options. Contact Hendrickson or vehicle manufacturer for availability.

** According to the publishers of THE TRUCK BLUE BOOK®, Class-8 tractors equipped with AIRTEK have a suggested incremental value of $800 compared to a truck equipped with an industry standard mechanical front suspension and I-beam axle
