Unlock The Full Potential Of Your Super Duty

If your Super Duty already looks tough but needs the performance to match, the ICON Stage 5 Suspension System is the upgrade that delivers on all fronts. With 4.5 inches of lift up front and heavy-duty 5-inch blocks in the rear, this system gives your truck the clearance it needs to run larger tires and conquer uneven ground without compromising ride quality. The real game changer here is ICON’s CDCV shock technology, giving you 10 levels of external compression adjustability so you can fine-tune how your truck responds on the road, at the job site, or deep into the backcountry. Whether you’re towing a trailer, crawling over rocks, or just driving daily, you can dial in the feel you want with a quick turn of the knob. You’ll also get better steering feel thanks to the ICON Centerline stabilizer with piggyback reservoir, which helps control feedback from oversized tires and rough surfaces. The radius arm drop brackets correct your front-end geometry, while the adjustable track bar keeps the front axle aligned under load. It’s a complete system that turns your truck into something far more capable, without sacrificing comfort or control.

High Performance Suspension With Precision Adjustability Built In

The ICON K64545 Stage 5 Suspension System is engineered for serious Super Duty owners who want more control and performance from their suspension. At the core of this system are ICON’s 2.5 Aluminum Series CDCV shocks, which feature remote reservoirs and 10-position compression adjusters. This allows you to dial in the damping rate for changing conditions or driving styles, whether you’re loaded up for work or exploring backcountry roads. Dual-rate coil springs up front are tuned for diesel applications, providing a softer initial ride and firmer response when fully compressed. The included radius arm drop brackets help maintain proper caster and front-end geometry while maximizing articulation. Rear lift is handled by robust 5-inch fabricated blocks paired with extended U-bolts, designed to handle towing, payload, and off-road abuse. Steering performance is refined by the Centerline stabilizer kit with a piggyback reservoir, which adds consistent damping for large tire setups. From front sway bar drop brackets to stainless steel brake lines, every component in this kit works together as a full-system upgrade, built for durability and tunability across all terrains.
