The company was best known for their Pro Shock suspension forks which used a coil spring design inside the headtube that slid on roller bearings. Without air seals, the forks provided very fluid action and excellent small-bump compliance. Of significance for custom frame builders, Action Tec offered fork kits which made integrating the forks into novel frame designs easier. Of historical significance were early 29ers and fat bikes. Doug Curtis of Curtlo Bicycles built a lot of frames with this fork and was also responsible for producing some of the frames Action Tec offered, including the aluminum Viper.
