Icon Vehicle Dynamics Ford F-250/F-350 4.5" Stage 1 Suspension System - K64521

PRODUCT OVERVIEW

The 2020-UP Ford Super Duty trucks sit at a lower ride height than 2017-2019 models, and although many of the 2017-2019 components will physically fit 2020 models, the resulting ride height is often taller than desired. So, engineers at ICON designed new progressive rate coil springs that achieve the correct advertised lift heights while still retaining the great ride quality, predictability, and performance that our Super Duty systems are known for.

This ICON Vehicle Dynamics 4.5" suspension system is a great way to lift your 4WD 2020-UP Ford F250/350 Super Duty while drastically improving ride quality and performance. This entry level system is perfect for on-road and towing use, as well as mild off-road use like job site duty and washboard gravel roads. ICON's 4.5" Stage 1 System is comprised of dual rate coil springs, radius arm drop brackets, adjustable track bar, 5" block kit, and ICON 2.0 Aluminum Series front and rear shocks. With the endless hours ICON has spent testing and tuning our suspension components and shocks as a complete package, you can rest assured you have the best suspension solution on the market.
