1979 is when it all began for ST in southern California. While NASA was monitoring the Voyager spacecraft and its outstanding images of Jupiter and its rings, and Phillips was demonstrating the Compact Disc for the first time, the team at ST was developing ways of getting the most out of your vehicles suspension.
In the years to follow, ST developed many innovative products and solutions in response to market demands. The success of the company and its core technologies attracted the attention of many tuners resulting in countless private label projects of what became many of the largest names in vehicle tuning in the USA over past 30 years.
The Sporttech & Speedtech lowering springs along with the ST Sway Bar kits became a household name in the tuning scene in the 80's and 90's, being referred to in many circles simply as ST. In 1995 this attention attracted a new owner, Belltech Sport Trucks, who brought a whole new dimension to the ST lineup, the wildly hot Sport Trucks. As part of the deal, ST was relocated from southern California to Fresno CA.
In 2005, the German suspension powerhouse KW automotive GmbH, well known worldwide for its reference standard KW Coilover height adjustable suspension systems, purchased both Belltech Sport Trucks and Suspension Techniques, and launched KW automotive North America Inc. now based just outside of Fresno in Sanger, CA. The infusion of technology from ST new parent company took ST's game to a whole new level, increasing not only its application range coverage, but also adding (among other things) the innovative ST Speedtech Coilover program, modeled after the wildly successful galvanized KW Variant 1 coilover program.
