ICON 2005+ Ford F-250/F-350 Super Duty 4WD 4in 2.5 Series Shocks VS RR CDCV Bolt-In Conversion Kit

61721C Overview
ICON's 2.5 VS Series Remote Reservoir Bolt-In Coilover Conversion Kit will add a new level of performance and adjustability to 2005-2025 F-250 and F-350 Super Duty pickup trucks. The advantage of utilizing a coilover conversion kit is that they have been designed to increase the overall damping ability of the vehicle while at the same time allowing for user-defined ride height adjustment. The 2.5" Remote Reservoir Coilover featured in these kits is based off of ICON’s 2.5 VS Series shock line - meaning that features like ICON engineered coil springs, FK Rod End bearings, and vehicle-specific valving come standard. Quality machined components and a fully serviceable design make for a product that will stand the test of time, yet retain the ability to be rebuilt or re-valved as necessary. ICON's exclusive Compression Damping Control Valves ICON’s CDC (Compression Damping Control) Valve option adds to the adjustability of these coilover conversion kits, allowing the end-user to adjust the ride characteristics of the vehicle with the turn of a knob. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle.
The 4-link brackets, upper links, and lower links are sold separately, allowing the 4-link system to be customized for your specific Ford Super Duty year range.
