Description
The American Forge & Foundry 90 Ft-lb Gold Torque Limiting Ext. (40091) is an essential tool designed to ensure the accurate and safe tightening of wheel lug nuts. This specialized extension prevents the common problem of overtightening, which can lead to significant damage to wheels, studs, and brake rotors. Crafted from professional-grade chrome molybdenum spring steel, it provides reliable performance and long-term durability in demanding automotive and fleet maintenance environments. Its unique design allows it to stop applying torque once the preset 90 ft-lbs is reached, providing consistent and precise fastening every time.
KEY FEATURES AND BENEFITS:
- Prevents Overtightening: Specifically engineered to limit torque application, significantly reducing the risk of over-stressing wheel lug nuts.
- Protects Vehicle Components: Safeguards critical parts like wheels, studs, and brake rotors from potential damage caused by inaccurate or excessive torque.
- Precision Torque Application: The extension stops turning once the exact 90 ft-lbs torque is achieved, ensuring uniform and accurate tightening.
- Built for Longevity: Constructed from high-quality chrome molybdenum spring steel, offering exceptional strength and a long service life.
- Corrosion and Scratch Resistance: Features a durable powder coat paint finish that provides superior protection against wear and environmental factors.
- Secure Socket Retention: Equipped with a ball detent that firmly holds sockets in place during operation, enhancing safety and efficiency.
- Effortless Identification: Size and torque rating are clearly roll-stamped directly onto the tool for quick and easy selection.
- Enhanced Clearance: Its long pattern design provides additional clearance from the tire, simplifying access in various wheel configurations.
- Impact Tool Compatibility: Designed for seamless integration with 1/2″ drive air impact tools, making it a versatile addition to any professional toolkit.

HOW TO USE:
- Select the Correct Socket: Choose the appropriate lug nut socket for your vehicle’s wheel nuts.
- Attach to Extension: Firmly attach the selected socket to the square drive end of the American Forge & Foundry 90 Ft-lb Gold Torque Limiting Extension.
- Connect to Impact Wrench: Insert the 1/2″ drive end of the torque limiting extension into your 1/2″ air impact wrench.
- Position on Lug Nut: Place the socket squarely onto the lug nut you intend to tighten.
- Engage Impact Wrench: Activate your air impact wrench. The extension will begin tightening the lug nut.
- Stop When Torque is Reached: Continue to apply power until the extension stops turning the lug nut. This indicates that the preset 90 ft-lbs torque has been achieved. The extension will then flex to absorb further impact, preventing overtightening.
- Repeat for All Lug Nuts: Follow these steps for all remaining lug nuts on the wheel, ensuring even and accurate torque across all fasteners.
