Weighing up to 275 pounds less than a typical 40,000-pound capacity suspension, Hendrickson's HTB® LT sets a new weight standard for drive-axle suspensions. The patented, non-torque reactive design helps deliver quiet, smooth operation with today’s high-torque engines without any torque restrictions. By controlling suspension windup and frame rise, HTB LT helps maximize the life of U-joints, pinion bearings, and other driveline components. Unlike other suspensions that carry the vertical load on a combination of steel and air springs, HTB LT rides on a full cushion of air. This unique design delivers exceptional ride, outstanding durability and reduced maintenance - factors that are important to owners and operators alike.
