QA1 Shocks, Rod Ends, and Suspension Components at JJ Motorsports
QA1, founded in 1993 by Jim Jordan in the USA, is a leading brand in the performance suspension industry, initially introducing rod ends and spherical bearings tailored for racing. Under the leadership of President & CEO Melissa Scoles, QA1 has expanded to offer high-quality shocks, struts, springs, and driveline components designed for muscle cars, classic trucks, circle track, drag racing, street performance, and street rodding applications.
At JJ Motorsports, we carry a robust selection of QA1 products to enhance your vehicle's handling and durability. For precise adjustments, the upper ball joint for GM/Pinto models provides a greasable, bolt-in solution with stock-length studs. Maintenance is simplified with tools like the rebuildable ball joint socket wrench, featuring a 1-inch socket and Allen key. Tune your shocks using the small body tuning kit for 7Q/8Q/70/82 series or the large body version for 5Q/6Q/51/53/60/62 series. We also offer essential rebuilds such as the bearing kit with snap rings for spherical bearings and the small body rebuild kit for 7Q/8Q series shocks. Whether you're building for the track or street, QA1 delivers reliable, high-performance options. Explore our inventory to find the perfect upgrades for your setup.
