Built To Take Your Super Duty Anywhere It Needs To Go

If you're looking to level up your truck’s ride without compromising comfort or capability, this ICON Stage 6 Suspension System with expansion packs is built for exactly that. Designed for 2023-2025 Ford F-250 and F-350 Super Duty diesel trucks, this kit transforms your suspension into something that feels as good on gravel or washboard as it does towing down the highway. Whether you're pushing through rough terrain or loading down the bed for a long haul, this system keeps your truck composed, confident, and ready for more. The 4.5-inch front lift combined with 2-inch rear expansion packs not only levels out the stance but also opens the door to more aggressive wheels and tires. This system doesn’t just lift, it redefines how your truck handles. From trail rides to job sites, it delivers balanced performance with rugged reliability. And with a tuned set of ICON 2.5 remote reservoir shocks at all four corners, your ride is ready for whatever the road, or the lack of one, throws at it.

Engineered Suspension Geometry That Works With You Not Against You

This Stage 6 system does more than just lift, it completely reconfigures how your suspension behaves under pressure. At the heart of the kit is ICON’s precision-engineered 4-Link system, which eliminates binding during suspension travel and maintains proper caster from full droop to full compression. The dual-rate coil springs up front offer a plush ride on the road and a firmer rate for off-road performance as the suspension cycles deeper. In the rear, expansion packs provide a clean 2 inches of lift while reducing axle wrap and improving ride quality under load. ICON’s 2.5 Aluminum Series shocks come tuned specifically for Super Duty diesel trucks, with remote reservoirs that help control heat during extended use. The system includes an adjustable track bar and heavy-duty drop brackets to dial in alignment and minimize bump steer. From daily driving to serious off-road excursions, every component is built to perform as a cohesive system, not just a stack of parts.
