QA1 invites you to upgrade your suspension with the top names in racing and street performance: QA1, Carrera Shocks, and Hal Shocks. 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.
