For the 2019–24 GMC Sierra 1500 Denali 4WD, Fabtech’s 6″ Basic System is engineered specifically to retain the vehicle’s exclusive Adaptive Ride Control (ARC) shock absorbers. These electronically controlled shocks respond to changing road conditions within milliseconds, delivering exceptional ride quality both on and off road. Fabtech’s system preserves this premium performance by using heavy-duty ARC shock relocation brackets designed for precise operation at the new lift height.
Fabtech’s engineering focus for this system was to achieve zero bump steer throughout the suspension cycle. Eliminating bump steer reduces driver fatigue and dramatically enhances overall drivability, especially on longer trips or uneven terrain.
A near-stock track width keeps oversized tires positioned neatly under the fenders for a clean, factory-like appearance. Fabtech’s proprietary steering knuckle geometry maintains an excellent lock-to-lock turning radius, ensuring the Sierra Denali can maneuver easily in tight areas.
Heavy-duty 1/4″ thick steel crossmembers incorporate OE-style alignment cam pins, allowing the factory cams to be reused for quick and accurate alignment adjustments. Triple differential mounts reposition the front differential for correct CV and driveshaft angles, ensuring vibration-free performance at higher speeds.
Rear lift is achieved by removing the factory 2″ block and replacing it with a 5″ block and U-bolt system. This creates a balanced stance while maintaining ARC system functionality.
Fabtech engineered every component of this Denali-specific system to ensure full compatibility with the ARC shocks at the full 6″ lift height. This premium suspension system includes Fabtech’s free 5-year / 60,000-mile Powertrain Warranty for added confidence and long-term protection.
