QA1 Precision Products Suspension Strut Assembly

QA1 Precision Products Suspension Strut Assemblies: Performance-Engineered for the Street and Strip

When it comes to upgrading your vehicle's suspension with components that bridge the gap between race-proven engineering and everyday drivability, QA1 Precision Products occupies a unique position in the performance aftermarket. Since 1993, QA1 has been an industry leader in high-performance suspension and driveline for the automotive aftermarket and various other industries. Their suspension strut assemblies reflect that deep engineering heritage — built not just to replace worn factory hardware, but to meaningfully improve how your vehicle handles, rides, and responds.

Monotube Construction and Adjustable Performance

QA1 is a leading manufacturer of high-performance suspension components, specializing in custom shocks, struts, and coilovers for a variety of industries, including automotive, motorsports, and off-road. Their strut assemblies lean heavily on monotube architecture, a design well-suited to performance applications because it separates the gas charge from the oil, reducing heat build-up and improving consistency under repeated compression and rebound cycles. Product lines such as the monotube strut body for the 1979–1993 Mustang — complete with bushings, wiper, and vent — highlight QA1's focus on direct-fit, performance-ready fitment.

QA1's adjustable shocks and struts are designed for fine-tuning suspension feel and performance, giving drivers the ability to dial in ride quality and handling characteristics rather than settling for a fixed, compromise valving. QA1 shocks and struts are available in multiple configurations and performance levels, designed for street driving, drag racing, and circle track racing. This multi-application approach means whether you're building a weekend cruiser, a track-day car, or a full-competition vehicle, there is likely a QA1 strut assembly engineered with your use case in mind.

Racing Pedigree Behind Every Part

In 1999, QA1 introduced racer-revalveable and rebuildable shocks for circle track racing, saving racers time and money. Over the next six years, QA1 fine-tuned and expanded its product offering by adding several shocks and struts engineered for street performance and circle track applications. That racing DNA carries directly into their strut assemblies — the same attention to valving precision, material quality, and rebuildability found on the track translates to products that outperform and outlast OEM units on public roads.

With over 83,000 square feet of manufacturing space in Lakeville, MN, QA1 is proud to offer an extensive line of American-made shock absorbers and accessories. QA1's quality system is certified to the ISO 9001:2015 standard, ensuring that every strut assembly leaving their facility meets rigorous, documented quality benchmarks — not just internal targets.

Who Are QA1 Strut Assemblies Built For?

QA1 specializes in providing performance shock absorbers, carbon fiber driveshafts, suspension, rod ends, spherical bearings, ball joints, and other related items to a variety of markets including circle track racing, drag racing, street performance, and street rodding. Their strut assemblies are especially well-regarded among classic Mustang, Camaro, Firebird, and GM muscle car builders who want a bolt-in upgrade that delivers measurable gains in cornering response and ride compliance. With trusted USA-made quality backed by a best-in-class warranty, they are a simple yet significant upgrade for your vehicle.

If you're evaluating a suspension overhaul, QA1's strut assemblies represent a compelling starting point — components with genuine motorsports roots, built in America, and engineered to be adjusted, serviced, and rebuilt rather than simply replaced.
