2.5 Smooth Body Shocks | DCA Piggyback Reservoir

The Dirt King 2.5 DCA Rear Shocks redefine what a heavy-duty suspension can feel like. Designed in parallel with the matching front shocks, this system delivers control, improved load handling, and a remarkably comfortable ride.

Each shock features independent high-speed and low-speed compression adjusters, giving you complete control over damping response. Firm up the settings for towing and hauling or soften them for a smoother, more compliant ride when unloaded.

After extensive tuning and real-world validation, these shocks deliver a stable, composed, and comfortable ride, maintaining confidence and control whether you're towing 10,000 pounds or driving empty down the highway.
