The QA1 Front Coil-Over Conversion Kit (MPN 52611-S650) provides a complete suspension overhaul for classic C10 trucks. This system replaces outdated factory suspension with a modern coil-over setup, allowing for precise ride height adjustment and significantly improved handling. By integrating tubular upper and lower control arms, the kit adds up to 7 degrees of increased caster, enhancing high-speed stability and steering feel. When paired with popular aftermarket drop spindles, this conversion can achieve up to a 5-inch drop for a perfect stance.

Built with performance-enhancing geometry and heavy-duty materials, this bolt-in kit is manufactured in the USA.
