The QA1 Pro Coil front system for 2007–2018 Silverado/Sierra 1500 (2WD) is a bolt-in replacement that makes ride height tuning straightforward—drop ranges vary with spindle choice. Fully threaded aluminum Pro Coil shock bodies allow easy height adjustment, and double-adjustable valving delivers independent rebound and compression control. The heavy-duty package uses durable bushings and a chromoly T-bar for truck duties.
