QA1 GS517-10750C Pro Front Coil-Over System - Single Adjustable - 10in x 750lbs/in - Select 1999-2006 Chevrolet Silverado/GMC Sierra 1500
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500.
The QA1 Pro Coil System provides a direct bolt-in solution for owners seeking superior valving control and a customizable stance. This single-adjustable system allows you to tune both compression and rebound valving simultaneously with a single knob, making it easy to find the ideal balance for street performance or drag racing. The lightweight billet aluminum shock body features a fully threaded exterior, enabling up to 2 inches of ride height adjustment for fine-tuning weight distribution and vehicle aesthetics.
This kit includes QA1’s American-made high-travel springs. These 750 lbs/in springs are engineered with a specialized wire diameter and fewer coils than standard springs, reducing unsprung weight and providing more travel. This results in a faster-reacting suspension that optimizes traction and ride quality. The system is designed to work seamlessly with factory control arms or upgraded QA1 tubular units.
