Steeda Autosports parts are all designed, engineered, and manufactured in the U.S. by their in house engineering staff using modern computer design software and CNC machine manufacturing. Steeda is also an ISO 9001:2008 certified company which is unique in the aftermarket/racing industry. This certification is part of a comprehensive quality management system which insures Steeda Autosports parts remain the best in the industry. Track tested and race proven, that is the Steeda Autosports difference.
