The QA1 GM Pro Front Coil-Over System is a high-performance suspension component designed for classic GM vehicles, including 1958-1970 Impalas, Full Size Chevy, Buick, Oldsmobile, and Pontiac models. Built with lightweight aluminum and featuring a fully threaded body, this coil-over system allows for precise ride height adjustment and valving control to optimize handling and stance. The system utilizes high travel springs with fewer coils and a smaller wire diameter, which increases travel and reduces unsprung weight for faster reaction and improved suspension performance. It offers multiple adjustable options, including independent compression and rebound, or simultaneous adjustments, making it suitable for a range of applications from street driving to racing.
Designed for direct bolt-in installation on full-size GM vehicles from 1958 to 1970, this coil-over system is ideal for enthusiasts seeking customizable suspension tuning. It is compatible with various models and can be adjusted to match individual driving styles, whether for casual street use or competitive racing. The kit includes a single coil-over shock with a large pigtail spring, and the shocks are 100% dyno tested, serialized, and serviceable through QA1 authorized centers. Made in the USA, this system enhances vehicle handling, ride quality, and stance, making it a versatile upgrade for street performance, autocross, road racing, and street rod applications.
