Dirt King 2.5 Smooth Body Shocks | DCA Remote Reservoir | 2011-2026 Sierra 2500 / Silverado 2500

Dirt King 2.5 DCA Front Shocks deliver enhanced stability, control, and ride comfort, supporting 1"-3" of lift when paired with torsion keys and featuring dual compression adjusters for precise tuning when towing, hauling, or daily driving.

The Dirt King 2.5 DCA front shocks were developed and tuned in tandem with the 2.5 DCA rear shocks to bring unmatched comfort, control, and stability to heavy-duty trucks. Designed for the unique demands of 2500-series torsion bar front ends, these shocks provide superior damping performance—whether towing, hauling, or daily driving.
Independent high-speed and low-speed compression adjusters allow you to tailor your setup for any driving condition—dial it firm for towing and hauling or soften it for a smooth, compliant ride on daily commutes. Built with hard-anodized 6061 aluminum bodies and remote reservoirs, they maintain consistent performance through long hauls and demanding use.
The result of countless tuning iterations and real-world testing, these shocks deliver a refined, balanced, and comfortable ride.
