ICON's 2.5 VS Series Remote Reservoir Bolt - In Coilover Conversion Kit will add a new level of performance and adjustability to 2005 - 2024 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 ICONs 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 ICONs 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.
