A Steering Stabilizer Kit is basically a horizontal shock absorber that helps to stabilize the steering system. The kit not only helps to stabilize the steering, but can also help in the prevention of "Bump Steer", when the steering wheel jerks suddenly as a result of hitting a pothole or object in your path. These kits will also help to reduce normal wear on vital suspension pieces, and make tires last longer. This kit is especially helpful for trucks whose original equipment tires have been replaced by larger or wider ones.
