Product Description

The QA1 GS517-10750C Single Adjustable Front Pro-Coil Kit is built for the 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500 2WD models with front coil-spring suspension. This complete front conversion kit features 10" free-height, 750 lb/in rate springs and single-adjustable coil-over shocks, giving you both ride-height control and tuned ride quality in one package.

With the threaded shock body, you'll gain roughly 0" to -2" of drop without altering the springs, while the single-dial valving allows you to dial in the ride feel from comfortable to firm. Installation is straightforward when used with either factory stamped control arms or optional QA1 tubular arms, allowing you to maintain proper geometry.

Ideal for enthusiasts building a lowered-stance street truck or upgrading their suspension for better performance on the '99-'06 GM 1500 2WD platform. Before purchasing, confirm your truck is 2WD with front coil springs, that your control arms are compatible, and that the 10" spring free height and 750 lb/in rate are appropriate for your front-end weight and wheel/tire size.
