When your normal wrench is not able to do the job on some stuck lug nuts, you really need to ramp up your torque! Our torque multiplier set includes a high-grade set of handle and wrench attachments, as well as the protective carrying case. The purpose here is to give extra leverage on tight bolts where a conventional tool is not going to give you the power you need to loosen them. An important part of any professional's tool kit, especially when working with cars and construction. Features: Perfect tool for trucks, RVs or any other heavy duty vehicles. Extended torque for hard to turn bolts. Everything included in package. Comes in durable plastic case for easy travel.
