ICON's 2.5 Series Bolt-In Coilover Conversion Kit will add a new level of performance and adjustability to Ford Super Duty trucks. They have been designed to increase the overall damping ability while also allowing ride height adjustment.
ICON's 2.5 VS Series Remote Reservoir Bolt-In Coilover Conversion Kit will add a new level of performance and adjustability to 2005-2026 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.
