Swift Springs

Swift Springs


Swift Springs was founded in 1997 as a motor sports division of Tokyo Hatsujo Manufacturing Co, Ltd. that has been leading the spring industry since 1924. The purpose was to demonstrate our superior engineering in spring by developing the next generation of motor sports suspension coil springs. They had to have the best characteristics of any brand or design in the market, which required the springs to be the lightest in weight and most durable, and to exhibit the most linear characteristics while still being cost effective.
