Frequently Asked Questions How do torque limiting extensions work with impact guns? These extensions use internal mechanisms that slip or disengage when the preset torque limit is reached, preventing your impact gun from applying excessive force to wheel nuts. This protects both the fasteners and the wheel from damage. Can I use these with regular sockets or just thin-wall impact sockets? While designed primarily for thin-wall impact sockets, these extensions work with any 1/2" drive socket. However, thin-wall sockets provide better clearance around wheel nuts and are recommended for professional use. How does this compare to using a torque wrench for final tightening? Torque limiting extensions provide consistent results during the initial tightening phase with impact tools, eliminating the need for separate torque wrench verification in most applications. This speeds up service while maintaining accuracy. What vehicles are compatible with this torque range? The 55-175 ft-lb range covers virtually all passenger cars, SUVs, and light trucks. This includes both foreign and domestic vehicles, making it a comprehensive solution for most tire service operations.
