From the family of ROADMASTER ACTIVE SUSPENSION comes a new and innovative engineering breakthrough for 1998 and newer Ford Crown Victoria Police cars, "ROADMASTER COIL PRO." When fitted to the rear coil springs of the vehicle, Coil Pro will greatly enhance the Safety, Road Handling, Carrying Capacity, and Performance without compromising the ride quality.

What Is It and How Does It Work?
Roadmaster Coil Pro is a worldwide patented product, engineered and manufactured in the USA, with over five years of development and testing behind it. The system consists of four sets of variable rated torsion spring assemblies. They are installed (two sets per coil spring), diagonally opposite each other. The installation is simple, only requiring 20 minutes, with no drilling or welding. Once installed the Coil Pro’s effect will be felt immediately. Coil Pro will reduce the dangerous body roll and sway of the vehicle at all speeds, thus enhancing performance and safety. This is achieved without compromising the ride quality, yet still providing 35% additional strength and support to the rear coil springs.
