Lock Technology 475 ft/lbs 3/4″ Drive Wheel Truck Extension (1600M)

The Lock Technology 475 ft/lbs 3/4″ Drive Wheel Truck Extension (1600M) is a professional-grade torque-limiting tool designed to prevent the over-tightening of lug nuts on heavy-duty truck wheels. This specialized extension acts as a precision torque controller when used with a 3/4″ drive impact wrench, flexing at a specific point to absorb excess force once it reaches its 475 ft/lbs limit. This controlled application of torque is essential for maintaining the integrity of wheel components, including the lug nuts, wheel studs, and rotors, all of which are susceptible to damage from improper tightening. The tool’s bright yellow powder-coated finish makes it easy to identify in a toolbox, and its robust construction from durable chrome molybdenum steel ensures it can withstand the demanding conditions of a professional service environment. By providing a consistent and accurate torque measurement, the LT1600M helps technicians comply with manufacturer specifications, reducing the risk of comebacks and ensuring safe, secure wheel mounting.

KEY FEATURES AND BENEFITS:

• Precision Torque Control: Accurately limits torque to 475 ft/lbs, preventing over-tightening of lug nuts on trucks and other heavy vehicles. This protects critical wheel components from damage.
• Enhanced Safety: Ensures that wheels are mounted with the correct torque, which is crucial for vehicle safety on the road, reducing the chance of wheels coming loose.
• Damage Prevention: The extension’s design prevents stripped threads, stretched wheel studs, and warped rotors, saving time and money on costly repairs.
• Ease of Use: This tool simplifies the wheel installation process by eliminating the guesswork of using an impact wrench. It is a simple, non-adjustable device that provides consistent results every time.
• Durable Construction: Made from chrome molybdenum steel, the extension is built to withstand high-impact use and provides long-lasting reliability without the need for recalibration.

SPECIFICATIONS:

• Torque Rating: 475 ft/lbs
• Drive Size: 3/4″
• Material: Chrome Molybdenum Steel
• Color: Yellow Powder Coat
• What’s Included: 1 Lock Technology 475 ft/lbs 3/4″ Drive Wheel Truck Extension (1600M)

HOW TO USE:

1. Select the Right Tool: Ensure your impact wrench and wheel socket are both 3/4″ drive to match the extension. The LT1600M is designed to work with a high-torque impact gun.
2. Attach the Extension: Connect the square male drive of the extension to the female drive of your impact wrench.
3. Attach the Socket: Secure your lug nut socket onto the square female drive of the extension.
4. Install the Wheel: Place the socket over the lug nut and begin tightening with your impact wrench. The extension will begin to flex slightly.
5. Stop When the Tool Flexes: Continue tightening until the tool visibly or audibly begins to “give” or flex. At this point, the extension has absorbed the excess torque, and the lug nut is at the proper 475 ft/lbs specification. Immediately release the trigger of the impact wrench.
