Hendrickson's lightweight, non-torque reactive HTB™ rear air
suspension system combines superior ride, improved stability, reduced
weight and reduced scheduled maintenance for on-highway trucks, with the additional benefits of a
smooth ride and reduced lifecycle costs. It is ideal for weight
sensitive applications such as bulk haul, refrigerated vans, and flatbed
operations.
Lightest in Class
Unique design and components make the HTB LT reliable and rugged, as well as
the lightest suspension in its class. Weighing just 700 pounds, HTB LT saves up to
250 pounds compared to industry standard 40,000-pound capacity suspensions.
Optimized Ride
HTB LT improves ride by as much as 34
percent over typical trailing-arm suspensions by supporting the entire load on
large volume air springs. HTB LT also has a highly optimized motion ratio since the
air spring and axle travel at the same rate.
Non-torque Reactive
HTB LT’s
parallelogram design significantly controls suspension windup and corresponding
frame rise. Maintaining pinion angles throughout axle travel reduces
suspension-induced driveline vibration and extends component life.
Reduced Maintenance
Zero Lubrication, all pivot points come equipped with premium
rubber bushings requiring no lubrication. Torque box bushings are designed for
long life.Reduced Re-torque — Re-torque of the clamp group is reduced
because no twisting is applied to the clamp group.
