Taking the knowledge and experience learned with the 4000 Series of dampers, AST is now building the new 5000 Series dampers.

The Story Behind AST Suspension
Advanced Suspension Technology (AST) has continuously evolved since its inception in 2000. From progressive lowering springs to 3-way adjustable dampers with external reservoirs, AST Suspension offers a wide range of products for almost any application.
AST Suspension was founded by Piet Kreeft and Peter Smits; their roots in suspension development and industrial manufacturing pushed the company to the forefront even in its early stages. For nearly 15 years, Piet supported professional auto and motorcycle racing for KONI Suspension at several prestigious circuits around the globe. Piet later left KONI to start Aragosta Suspension, becoming a leader in both motocross and GP racing. Aragosta built upon his success and expanded the product range to include most vehicle applications. Piet later formed HI TECH, where he worked with INDY cars and was very active in the chassis and suspension space.
After leaving HI TECH, Piet formed AST with Peter Smits of Smits Factory in 2000. Together, the knowledgeable pair combined their years of technical expertise to design and construct new suspension systems. AST earned its name through unparalleled quality control and manufacturing flexibility, setting it apart from the competition in the suspension industry. Apart from its impressive sport and street damper product lineup, AST also succeeded in European motorsports.
AST Suspension in North America
AST Suspension NA was established to offer the U.S. the same high-performance shocks used by enthusiasts and race teams throughout Europe. With a demanding market for more powerful vehicles, handling and control is just as important to keep that power in check.
AST Suspension NA was formed and is headquartered in Irvine, California, at the heart of the U.S. automotive industry. The U.S. team specializes in serving the North American market via sales, product support, and service, working directly with the AST and Moton headquarters in Holland.
