THE ULTIMATE IN PERFORMANCE SUSPENSION
Est. 1999, Extensive Testing, Superior Knowledge

All of our coilovers are hand assembled and shock dyno’d to ensure you receive a high quality, reliable, and affordable product.

Our Story

In 1999 after years of racing time attack and constantly changing suspension setups realizing they all had major flaws. It became obvious there wasn’t a quality performance suspension on the market, Soon after with lots of trials and tribulations Silver’s was born. Silver’s combines both the passion for automotive racing and the knowledge of the industry. Silver’s was started with the performance comes first mindset, and to this day 19 years later it still stays true to that. Every kit is designed with track performance in mind, with equal focus on reliability.

Our Mission

We strive to bring you the best performing suspension at an affordable price. Every part of our coilovers is manufactured in our 36,000sqft state of the art facility. Our kits are hand assembled and every single shock is put on the dyno to ensure it is within the 5% variation we allow to pass. This is much lower than most manufacturers and there is no spot checking. Doing everything in house allows us to insure we have the best quality possible.
