Description 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.
