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.
