QA1

QA1 started in 1993 building rod ends, spherical bearings and custom linkages for racers, then moved into shock manufacturing with the purchase of Hal Shocks in 1998 and Carrera Shocks in 2004. Today the company designs and builds shocks, struts, suspension components and carbon composite driveshafts in more than 100,000 square feet of its own manufacturing space in Lakeville, Minnesota, under an ISO 9001 certified quality system.
