QA1 Shocks

QA1’s Jim Jordan started his company with a desire to impact the performance racing world. His company jumped into the market with rod ends and spherical bearings, but in 1998, after five years in business, QA1 purchased Hal Shocks and started making shock absorbers for the drag strip. With their rebuildable shock line from 1999, QA1 underscored their care for the racer by offering a long-term solution for circle-track racing suspension. By 2004, QA1 was the number one producer of performance racing shocks, and in 2011, several more acquisitions solidified QA1 as the market leader. If you’re looking for the best suspension for your racing Corvette, Zip’s line of QA1 products is a fantastic choice.
