THE BEGINNING

Competition Suspension was founded in 2009 with the goal of bridging the technology gap in the racing industry. We recognized that short track teams lacked access to the advanced shock technologies prevalent in IndyCar and NASCAR. Our mission was to provide reasonably priced, high-quality shocks that utilized these same cutting-edge technologies.  Our first set of CSI Shocks, built for Nic Faas in April 2009, led to a win in their debut race. Since then, our commitment to building the best shocks in the industry, without cutting corners, has remained unwavering. As a result, CSI has become the preferred shock for many top professionals today. We are proud to have contributed to over 5,000 race wins and numerous track, regional, and National Championships worldwide.

THE PRESENT

CSI is a family-owned business located in Brownsburg, Indiana, just west of Indianapolis. Our 12,000-square-foot facility is surrounded by professional race teams, and our entire staff is deeply involved in racing. We handle every aspect of our products, from concept to completion, all under one roof.  We are excited to share that some great new products are in development for the 2026 season. Our focus remains 100% on the quality of our products and the success of our customers' race programs. We founded this company on a few simple principles: to build the highest quality suspension components and support them with industry-leading customer service. We have upheld these principles throughout our tremendous growth over the past fourteen years.

THE FUTURE

At CSI, our passion for what we do drives us every day. We are constantly striving for perfection, pushing the boundaries of technology to enhance the performance of our shocks and components.
We're also expanding our presence, traveling to more races across the country and staying on top of the latest trends to better assist you.  A significant development for us was bringing all manufacturing in-house in 2022. With six Hurco CNC mills and lathes, we can now bring new ideas to market faster and improve the overall quality of our products.  Thank you for choosing CSI and for being a part of our growing family business.
