AirTek delivers improved ride, stability and handling for IC Bus type D rear engine buses in axle ratings of 12,000 and 14,000 pounds. High-volume air springs support approximately half of the vertical load to soften the ride, and dual height control valves react quickly on rough roads to maintain proper ride height.
The leaf spring assembly forms a torsion system with the SteerTek axle, enhancing roll stability characteristics. The box-shaped axle resists horizontal, vertical, and twisting forces more effectively than traditional I-beam axles.
Hendrickson's SteerTek axle features a two-piece knuckle to simplify serviceability by allowing kingpin maintenance without removal from the axle beam. Optimized steering geometry reduces "bump steer" and "wheel kick" over uneven terrain.
Rubber suspension bushings eliminate lubrication requirements while reducing twist and flex in front spring connections to improve driver road feel. Up to 50 degrees of wheel cut provide maneuverability in tough road conditions.
