QA1 hits the sweet spot of race-proven engineering and bolt-on convenience for classic muscle and street/strip builds - a genuine upgrade path from worn factory suspension to modern handling.

QA1 manufactures its shocks, coilovers and carbon fiber driveshafts in Lakeville, Minnesota, and its adjustable shock technology lets you tune rebound and compression without removing anything from the car.

QA1 has been engineering American-made performance suspension since 1993 from its Lakeville, Minnesota factory. Best known for rebuildable shocks and coilover systems for drag racing, circle track, and classic muscle, QA1 also builds ball joints, rod ends, tubular control arms, K-members, and ultra-light carbon fiber driveshafts. Whether you are putting a Nova on coilovers or cutting sixty-foots in a Fox Body, QA1 parts are designed, tested, and manufactured in the USA.
