ICON 2017+ Ford F-250/350 7in Stage 5 Suspension System w/ Radius Arm

ICON's Stage 5 suspension system for the 2017-2022 Ford F-250 and F-350 Super Duty is their radius arm-equipped package that provides 7 inches of lift. At this level, ICON replaces the factory radius arms with their own fabricated units, and the difference in how the front end behaves is significant.

The ICON radius arms use a sealed pivot bushing that minimizes road feedback while ensuring quiet operation and a long service life. Unlike the factory arms, these are fabricated with a fully boxed design that provides the strength needed at aggressive ride heights. The profile has been specifically optimized for tire clearance at full steering lock, which means a 37-inch tall tire clears without contacting the radius arm. That is a detail that matters when you are maneuvering tight trails or parking lots with large tires -- contact at full lock is a common complaint on lifted Super Duty trucks running aftermarket radius arms that were not designed with this clearance in mind.

As a Stage 5 system, this kit sits above the Stage 4 in ICON's lineup. The radius arm upgrade is the key differentiator, adding improved front-end feedback and tire clearance on top of the comprehensive lift components. The full package addresses both front and rear, so you get a matched system rather than individual parts from different stages or manufacturers.

This ships in multiple boxes. At this price point and complexity level, professional installation is strongly recommended, and a full alignment after install is essential for safe handling and even tire wear at the new ride height.
