This is a demo for a TORQUE MULTIPLYING LUG WRENCH, 1:78 gear ratio, Heavy-Duty Model, as seen on EZLugWrench.com designed to remove even the most difficult lug nuts from trucks, buses, semi-trucks, moving vans, tractors, farm equipment, and RVs without the use of an impact wrench or air compressor. It is a manual, yet more efficient tool and more practical than an impact wrench, especially when you need to repair a tire on your own.
