Founded in the early 80’s in Southern California, under the company name of Suspension Techniques. Suspension Techniques developed many innovative products and solutions in response to market demands. Utilizing quality materials, modern technologies and streamline processes. Suspension Techniques was able to provide excellent value for their product in the marketplace. Suspension Techniques soon established themselves as a recognized name the Sport Compact suspension tuning industry. This success helped garner the attention of many enthusiasts and tuners resulting in a strong growth in the brand in the USA.

The Sporttech & Speedtech lowering springs along with the Suspension Techniques 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. With the acquisition ST was relocated from southern California to Fresno CA.

In 2005, the German suspension manufacturer KW automotive GmbH, well known internationally for their KW Coilover height adjustable suspension systems, purchased both Belltech Sport Trucks and Suspension Techniques and launched KW automotive North America Inc. With the name purchase can a formal name change of the brand to it’s current nameplate of “ST suspensions”. The infusion of technology from ST’s 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 Coilover program, modeled after a galvanized KW Variant 1 coilover design.

With this influx of worldwide technology, staff, and engineering base. ST boasts one of the largest application ranges and largest distribution chains of any suspension manufacturer in North America.
