QA1 was founded in 1993 and quickly became the #1 name in rod ends and spherical bearings sold into performance racing. In 1998, QA1 entered the drag racing market with the purchase of Hal Shocks. Over the next six years, QA1 improved the products and added shocks and struts engineered for street performance and circle track applications. In 2004, QA1 purchased Carrera Shocks and is now the #1 manufacturer of performance racing shocks. QA1 now has an even wider selection of products available, such as double adjustable, monotube, gas pressurized and chrome plated shocks and springs. Whether you’re looking for improved ride quality, show-stopping appearance, or faster times, QA1 delivers. QA1 utilizes many unique processes and components in its shock absorbers, with a tremendous selection available. Deflective disc valving, gas charged, monotube, twin tube, single adjustable, double adjustable, chrome plated … the list goes on and on. We even offer a complete line of racer revalveable, rebuildable and repairable circle track and stock mount shocks. Chances are great that if you want it, we’ve got it – and at a reasonable price. Other Suspension Components QA1 also offers many other complementary suspension components, such as k-members, caster/camber plates, control arms and struts for select applications. In addition, coil-over conversion kits and many other items are available for many popular applications. To complement the QA1 shock absorbers, we have also engineered a complete line of coil-over springs. QA1 springs are manufactured with the highest quality chrome silicone wire available. Springs are double heat-treated, double shot-peened and either powder coated with a chrome appearance or chrome plated. Each spring has been designed to be as light as possible without sacrificing performance. Every QA1 product has been engineered to outperform the competition at an affordable price.
