Competition Suspension

What Competition Suspension does

Competition Suspension, Inc., doing business as CSI Shocks, is a privately held, Brownsburg, Indiana-based manufacturer of aftermarket racing suspension components founded in 2009. The company designs and produces high-performance shock absorbers, torsion bars, springs, steering components, bump stops, and related rebuild parts targeted primarily at short track racing disciplines — wing sprint cars, non-wing sprints, 600cc micros, Jr. Sprints, 1000/1200 mini sprints, dirt midgets, pavement open wheel, Silver Crown, and quarter midgets. Its technology stack includes the RS-JR4 shock architecture with a floating seal head to minimize drag and improve response, oil-impregnated bronze torsion bar bushings with a recessed bore barrier, in-house CNC machining of 6061-T6 aluminum, hard-coated (CSI 'Gold') machined steel shafts, tuned deflective disc basevalves, and a billet aluminum cockpit adjuster with eight detents per turn that is engineered for cross-brand compatibility with CSI, Afco, JRI, and Penske shocks.

The business model is largely direct-to-consumer via the company's own BigCommerce-powered e-commerce storefront (csishocks.com), supplemented by a domestic dealer network and on-site track support. Pricing is per-unit, with individual components ranging from under $10 (valve components, cable assemblies from $6.99) to over $500 for full shocks (e.g., the NXT-LT26 at $349.99) and complete shock packages for specific racing applications. Free shipping is offered on orders over $299.99, and ancillary revenue is generated through branded apparel (hats, shirts, sweatshirts, jackets), decals, and gift cards. Customers are competitive racing teams and individual enthusiasts segmented by racing category, making this a vertically segmented, niche-market business with no disclosed enterprise contracts or large-channel OEM relationships.

CSI Shocks is independently operated with no disclosed venture capital, private equity, or strategic ownership, and discloses no financial metrics, headcount, or institutional investors. Marketing relies on the company website, a YouTube educational channel (with shock rebuild tutorials), an email newsletter, and physical track-side presence. The company also distributes complementary third-party brands — KSE steering, Eibach, Hyperco/Hypercoil, Landrum, and Swift springs, plus Schroeder torsion bar bushings and Schrader valve products — to round out its catalog. Geographic scope is exclusively United States.
