Said to save up to 263 lbs. over competing rear air suspensions, the Hendrickson HTB LT is now available on the International ProStar, according to Hendrickson Truck Suspension Systems.

A non-torque reactive rear air suspension with a torque box system said to improve multi-axial stability and control, the HTB LT is the lightest 40,000-lb. capacity air suspension in its class, according to Hendrickson. Its air springs carry the entire vertical load, reducing vibration and ride harshness compares to systems that spread the load between air and leaf springs, the company says.

The HTB LT’s design features parallelogram geometry, which eliminates leaf springs and reduces components for additional weight savings. It also features cross-members, frame hangers and torque roads designed to further reduce weight, parts count and complexity, Hendrickson says.
