Ford F150 Shock Absorber Set - Rear - ICON - 2.5 Series Piggyback Reservoir - `21-`23. These ICON V.S. 2.5 piggyback rear shocks are vehicle-specific rebuildable monotubes tuned for the '21–'23 F-150 rear applications, offering improved control off-road and a composed ride on the street.

Built with application-specific valving and lengths, these shocks feature a piggyback reservoir for better heat dissipation and an internal "Bump Zone" that increases damping by roughly 20% near full compression to help control high-speed impacts and reduce harsh bottom-outs. The one-piece digressive piston, premium 5WT oil and nitrogen-charged design deliver consistent damping across temperatures. These shocks are 100% rebuildable and revalveable and can be upgraded to ICON’s Compression Damping Control Valve (CDCV) for more user-defined tuning.
