Description
The Lock Technology Yellow 65ft/lbs 1/2″ Drive Torque Extension (1400F) is a specialized tool engineered to provide a simple and effective solution for tightening lug nuts to their correct torque. This torque extension bar, also known as a torque stick, is designed to be used with a 1/2-inch drive impact wrench. Its primary function is to prevent the over-torquing of wheel nuts, which is a common problem that can lead to significant damage. By flexing once the specified torque of 65 ft-lbs is reached, it absorbs additional force from the impact wrench, thus protecting wheels, wheel studs, and rotors from the harm caused by excessive tightening. The tool’s distinctive yellow color makes it easily identifiable for quick use in any professional or home garage setting. The design is compatible with a wide range of vehicles, including most foreign and domestic cars and light trucks, and can be used with both standard and thin-wall lug nut sockets. This is particularly important for modern vehicles that have tight tolerances around the wheel nuts, as it helps eliminate damage to the wheel’s finish.
KEY FEATURES AND BENEFITS:
- Reliable method for tightening lug nuts to the correct torque, reducing the need for re-checking.
- Calibrated design prevents stripped threads, broken studs, and warped rotors from excessive force.
- Works with both thin-wall and standard lug nut sockets for versatility and protection of wheel finishes.
- Yellow color coding allows quick identification of the tool.
