Pro-Coil Kit - Front GM Fullsize

The Pro-Coil Kit - Front GM Fullsize from QA1 is a purpose-built front suspension upgrade engineered for GM full-size trucks and SUVs seeking improved handling, load capacity, and ride quality. Whether you're building a lifted truck, daily-driving a Silverado or Sierra, or preparing a vehicle for towing duty, this coil spring system delivers the structural support needed to handle modern demands. QA1 has established itself as a trusted name in suspension geometry, and this kit reflects that commitment to precision engineering and durability in the competitive fullsize market.

The Pro-Coil Kit replaces OEM coil springs with high-performance coils calibrated to maintain proper suspension geometry under load, body roll reduction during cornering, and consistent ride height whether empty or fully laden. QA1 springs are manufactured to exacting tolerances with premium steel construction, ensuring minimal spring sag over time—a critical factor that separates quality upgrades from budget alternatives. The front fitment addresses geometry constraints specific to GM fullsize platforms, with spring rates and damping characteristics optimized to work in concert with factory or upgraded shocks for balanced performance across highway cruising and off-road applications.

This upgrade benefits truck owners and enthusiasts running daily drivers, weekend warriors, or vehicles modified with aftermarket wheels, tires, or payload. Installation pairs best with quality shock absorbers to maximize damping response and longevity. The kit's 28.48 lb weight and compact 6 x 6 x 25 inch shipping profile make logistics straightforward, though professional installation is recommended to ensure proper spring seating, alignment verification, and safety checks before returning to service.
