The QA1 GM Pro Front Coil-Over System, part number qapGD401-10400B, is designed for precise suspension tuning in classic Pontiac LeMans models from 1969 to 1972. Featuring a fully adjustable coil-over shock with double adjustable compression and rebound, this system allows you to fine-tune ride height and damping characteristics for optimal handling and comfort. The shocks have a compressed length of approximately 10.13 inches and an extended length of about 14 inches, providing versatile suspension travel to suit street or racing applications. The kit includes a 10-inch spring rated at 400 pounds per inch, with a tapered flat end for secure seating and durability. Made in the USA, these lightweight, high-travel springs utilize fewer coils and a smaller wire diameter, which increases suspension travel and reduces unsprung weight, resulting in quicker reaction times and improved handling dynamics. The fully threaded body design allows for easy ride height adjustments, enabling you to achieve the desired stance or fine-tune weight distribution for enhanced performance. These coil-over shocks are compatible with factory or upgraded control arms, making installation straightforward and versatile. They are ideal for a variety of applications, including street performance, autocross, drag racing, and road racing, providing customizable damping for different driving styles. The system is 100% dyno tested and serialized for quality assurance, and it is serviceable and rebuildable at authorized QA1 service centers. Whether you're aiming for improved handling or a custom stance, the QA1 GM Pro Coil-Over System delivers dependable, American-made performance with a limited lifetime warranty, ensuring peace of mind and long-term durability.
