QA1 GM Pro Front Coil-Over System - Double Adjustable (Pigtail Mount)

Enhance the performance and adjustability of your classic GM vehicle with the QA1 GM Pro Front Coil-Over System. This system is designed for a wide range of applications, from classic Tri-Five Chevys to early GM A-bodies, offering superior ride height and damping control. Achieve a perfect stance and optimized handling for street, strip, or track use.

Key Features & Benefits:

  • Double Adjustable Valving: Fine-tune your suspension's compression and rebound characteristics independently. This allows for precise control over ride comfort and handling response, catering to your specific driving needs.
  • Adjustable Ride Height: The fully threaded shock body enables easy and accurate adjustment of your vehicle's ride height. Lowering the center of gravity improves cornering and allows for a more aggressive aesthetic.
  • Lightweight High Travel Springs: Includes American-made, lightweight springs (10-inch length, 450 lb/in rate) designed for increased travel, reduced unsprung weight, and faster suspension response. The pigtail mount design ensures secure installation.
  • Versatile Fitment: Suitable for a broad spectrum of classic GM vehicles, including 1955-1957 Chevrolet Bel Air/Truck/Two-Ten Series, and 1964-1966 Buick/Chevrolet/Oldsmobile/Pontiac models.
  • Durable Construction: Built with high-quality aluminum components for reduced weight and long-lasting performance.

The QA1 GM Pro Front Coil-Over System provides a significant upgrade over stock suspension, offering unparalleled adjustability and performance benefits. Perfect for hot rods, muscle cars, and pro-touring builds.

Upgrade your classic GM with QA1 Pro Coil-Over Systems from GGCRACING.
