Performance Suspension. Since 1993.
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.

Full-vehicle suspension kits for GM A/B/G/F/X-body, Mopar & Mustang

Rod ends, spherical bearings, jam nuts & linkages

QA1 builds for street performance, drag racing, circle track and street rods — most shocks are single or double adjustable, so ride and rebound can be dialed in after the car is on the ground.
