Product Description

The Roush 422308 Super Duty Suspension Kit delivers a clean, performance-oriented upgrade for 2017-2026 Ford Super Duty trucks (F-250/F-350/F-450), excluding the Tremor trim. By combining a 1.5-inch front lift with premium FOX 2.0 strategic dampers and a Roush-tuned coil spring set, this kit improves both stance and capability without sacrificing factory towing or ride quality.

Whether you're looking to level your Super Duty's factory rake, improve off-road stability, or simply upgrade the ride for heavy-duty driving, this kit targets the response and durability demands of truck owners who expect performance under load. Because the kit is engineered specifically for the Super Duty platform (rather than being a one-size-fits-all solution), installation results in tight fitment, optimized geometry, and confidence under both daily driving and hard-use conditions.

Installation requires alignment and moderate mechanical skill (approximately 4.5-5 hours) as front lift geometry is altered. Ensure 2WD/4WD variant compatibility and avoid Tremor-badged trucks per Roush's exclusion. Once installed, you'll benefit from improved ride quality, reduced body roll under load, and enhanced overall driving dynamics. Upgrade your Super Duty with a kit built from the same components used on Roush production vehicles.
