OVERVIEW ICON's 2.5 VS Series Remote Reservoir Bolt-In Coilover Conversion Kit will add a new level of performance and adjustability to 2005-2016 F-250 and F-350 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 Eibach coil springs, FK Rod End bearings, and vehicle-specific valving come standard. Rear 2.5 Aluminum Series piggyback shocks feature one-piece impact extruded aluminum cylinders that offer lighter weight, improved corrosion resistance, and a more uniform finish than traditional plated steel cylinders. 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. FEATURES & BENEFITS FK Rod End bearings for extended longevity and minimal deflection Bolt-in system fits in OE coil bucket location Ride height adjustable coilovers (2.5-3") Decreased body roll and improved on and off-road ride dynamics Vehicle-specific shock valving provides unparalleled ride quality and control Shocks are fully rebuildable and revalveable Coilover conversion allows for addition of secondary shock Corrosion resistant CAD plated coilover shock body with 7/8" shaft Rear shocks feature anodized, one-piece impact extruded aluminum shock bodies Eibach coil springs guaranteed for life against sagging or breakage DOWNLOAD INSTALLATION GUIDE 64035 61720 37705P WARRANTY TECH INFO: OEM Wheels & Tires Fitment: Yes Recommended Aftermarket Wheels: ICON Alloys | 17x8.5" w/ 5.00” Backspace / 6mm Offset Recommended Aftermarket Wheels: ICON Alloys | 18x9" w/ 5.25” Backspace / 6mm Offset Recommended Aftermarket Wheels: ICON Alloys | 20x9" w/ 5.25” Backspace / 6mm Offset Recommended Aftermarket Tires: 35" x 12.50" (Larger tires may fit but fender trimming and modifications will be required.)
