Product Description

The QA1 52626-D700 Double-Adjustable Front Coil-Over System is engineered for the 1999-2006 GM Silverado and GMC Sierra 1500 trucks (2WD) to deliver advanced suspension performance in a complete front end upgrade. Featuring high-rate 700 lb/in springs and QA1's double-adjustable coil-overs, this kit allows fine tuning of ride quality, stance and handling dynamics while replacing the stock setup for modern precision.

By including tubular upper and lower control arms, the system improves front geometry and supports larger wheel/tire setups, while offering ride height adjustability up to 5" with optional spindles. The bolt-in installation design ensures compatibility with factory mounts, simplifying the upgrade process while delivering serious performance gains. Ideal for show, street, or performance trucks seeking premium suspension behavior and tuning flexibility.

Before installation, verify the vehicle's front end is the factory coil front setup, confirm compatibility with your wheels/tires and drop spindles if used, and plan for post-install alignment to ensure proper caster, camber and toe settings. With the QA1 52626-D700 kit installed, you'll gain a refined, adjustable, and purpose-built front suspension system built for serious performance.
