Lock Technology Drive Torque Extension Bar for Trucks

The LTI Tools 1600 Series Torque Master Truck Extensions are precision-calibrated torque-limiting bars designed for heavy-duty service applications including fleet maintenance, commercial truck repair, and industrial vehicle service.

Available in both 3/4″ and 1″ drive configurations, each extension delivers consistent torque output ranging from 175 to 550 ft-lbs, making them ideal for safely tightening wheel lug nuts, hubs, suspension bolts, and more. These tools help prevent over-torquing when used with impact wrenches and eliminate the need for manual torque wrenches in high-volume environments.
