What is the difference between Stage 3 and Stage 4 for this truck?

The Stage 4 upgrades from 2.0-inch body shocks to 2.5-inch piggyback reservoir shocks. The larger shocks hold more oil, run cooler, and provide more consistent damping under heavy or sustained use. The rear also uses progressive rate leaf springs instead of blocks.

Can this system be used while towing?

ICON designed this system with the goal of maintaining the Super Duty's towing capacity. Their engineers specifically note that they aimed to produce a suspension that maintained towing capability while adding 7 inches of lift.

What tire size will clear after installing this lift?

ICON states the system yields enough clearance for 37-inch tires. Actual clearance depends on wheel offset and trim, so confirm your specific tire and wheel combination with ICON.

Product Details

ICON's Stage 4 system raises the 2008-2010 Ford F-250 and F-350 Super Duty a full 7 inches while aiming to maintain the truck's towing capability. Where the Stage 3 uses 2.0-inch body shocks, this Stage 4 steps up to 2.5-inch Series piggyback reservoir shocks at all four corners, which hold more oil and run cooler during extended heavy use like towing on mountain grades or sustained off-road driving.

Up front, 7-inch lift dual rate coil springs pair with fabricated radius arm drop mounts that carry brushed stainless badges. A track bar drop bracket, bump stop extensions, sway bar links, forged pitman arm, and brake line brackets round out the front end. Each piece addresses the geometry changes that come with lifting a solid-axle truck this much, keeping the steering, braking, and sway bar function working as intended.

In the rear, ICON uses 5-inch lift progressive rate leaf springs with U-bolts instead of blocks. Progressive rate springs get stiffer as they compress, which helps the truck handle both empty and loaded conditions without a harsh ride when unloaded. ICON states this system clears 37-inch tires. At nearly $6,000, this is a considered purchase for a serious build, and professional installation is strongly recommended given the scope of the component replacement.
