Fantastic tool for racers and anyone else looking to easily and quickly remove wheels from the vehicle


The Road Side Impact Wrench sells on Amazon.com for $47.91 and is roughly the size of a drill. It uses half-inch drive sockets and comes with two sockets with dual sizes for lug nuts on each end. The device uses the DC outlet in your car for power to operate. It comes in hard black plastic case to put in the trunk of your car.

In Use

I mentioned a few times around here that I like to road race my Mustang. As my experience increased and I started driving faster on the racetrack I came to a point where I could no longer use normal brake pads due to brake fade. The problem with moving away from brake pads that will work on the street to brake pads that will work on racetrack is that racetrack pads will not work on the highways because they don't get hot enough to function correctly. Swapping pads means I have to take off both front wheels, and that can get tiring very tedious with the normal lug wrench.

I ran across this Kawasaki 12 V DC Road Side Impact Wrench and figured it was perfect thing to make removing the lug nuts on the wheels easier and faster. This impact wrench is designed to be kept in the back of your car to be used in a roadside emergency rather than a normal lug wrench. All you have to do to get the wrench power is plug it into your DC outlet inside the car. The cord is about 10 feet long so it should work for the vast majority of vehicles on the market.

The best part is that the Kawasaki 12 V DC Road Side Impact Wrench delivers 280 foot-pounds of maximum torque allowing it to remove all but the very tightest lug nuts. If this thing can't remove the lug nuts on your wheels, the chances of you removing them with the normal lug wrench are slim. The way to use this tool is to plug it in to begin with, pick the correct socket for your lug nuts, and then place the lug nut inside the socket and pull the trigger on the tool.

The first thing that happens is the internal motor spins up the impact device inside the drill. For the first 10 to 20 seconds you will hear the whirring sound and nothing will happen. After that period, the impact function begins, and it sounds and feels like a small hammer banging around inside the Kawasaki 12 V DC Road Side Impact Wrench. It is that hammering effect where the tool gets the impact name and the power to remove very tight lug nuts.

Depending on how tight the lug nuts on the vehicle are, it will take more or less time for the impact wrench to break the lug nuts free. Since I race my car on the road track, I torque the lug nuts pretty tight at 100 foot-pounds. The Kawasaki 12 V DC Road Side Impact Wrench broke the lug nuts free in about 15 seconds each. You have to be careful to not press the impact wrench very tightly against the lug nut, because that keeps it from spinning up to the proper speed initiating impact action. All you have to do is place the socket gently on the lug nuts and pull the trigger. The Kawasaki 12 V DC Road Side Impact Wrench does all the work for you. After you swap the tires or fix a flat, you reverse the direction and you can put the lug nuts back on tightly using impact wrench.

The only downside I ran into was that the sockets that are included with the Kawasaki 12 V DC Road Side Impact Wrench are to big around to fit inside the holes where the lug nuts sit on my wheels. Luckily, I use spline lock lug nuts so there is a long adapter allowing for plenty of clearance. You may have to buy a thinner wall or longer socket to fit your vehicle. The good news is any half-inch drive socket will work with the Kawasaki 12 V DC Road Side Impact Wrench. The handle of the impact wrench also has a bright LED light making it easy use in the dark.
