ICON 2017+ Ford F-250/F-350 2.5-3in Stage 3 Coilover Conversion System - K63143

ICON's 2.5 VS Series Remote Reservoir Bolt-In Coilover Conversion Kit will add a new level of performance and adjustability to 2017-2023 F-250 and F-350 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 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.

TECH NOTE: Due to tight clearances and varying placement of vehicle’s wiring harness in the upper front-passenger wheel well area, installer must ensure adequate clearance between the harness, coilover reservoir, and other components to prevent chafing/damage to wire harness. If adequate clearance cannot be achieved, please contact ICON Customer Service.
