3.0 Series Remote Reservoir Rear Coilover Pair for 2005-2026 Ford F-250 and F-350
The ICO61804CP ICON Vehicle Dynamics 3.0 Series VS Remote Reservoir CDCV rear coilover pair provides superior adjustable damping for 2005 through 2026 Ford F-250 and F-350 Super Duty 4WD trucks. Supporting 0 to 3 inches of rear lift over stock, the ICO61804CP replaces factory rear shocks with a monotube nitrogen-charged unit featuring an external Compression Damping Control Valve (CDCV) for fine-tuned adjustment of the shock's compression response. The 3.0 inch body diameter delivers 50% more piston surface area versus ICON's 2.5 Series, improving damping consistency and heat rejection under sustained use.

What is the CDCV adjustment on this shock?
CDCV stands for Compression Damping Control Valve. It is an external adjustment valve that allows the user to change the compression damping rate without removing the shock from the vehicle.
How does ICO61804CP differ from ICO61804EP?
The ICO61804CP covers 2005-2026 model years, while the ICO61804EP is specific to 2017-2026. Confirm your year before ordering.
