Lifting your 2023+ Super Duty shouldn’t mean giving up the things that make it a Super Duty in the first place. The AEV 4" DualSport RT Suspension System was engineered to increase off-road capability and ground clearance — without sacrificing ride quality, steering precision, or load-carrying stability. This isn’t a “tall for the sake of tall” lift. It’s a fully engineered suspension system designed to work as one cohesive package. Big Tire Clearance. Zero Compromise. With just 4 inches of lift, the DualSport RT Suspension System allows you to run up to a 40” tire when combined with AEV HighMark Fender Flares (37” tire without HighMark Fender Flares) while maintaining proper suspension geometry, steering feel, and payload capability. More clearance. More capability. No drama on the highway. What Makes It Different? Most lift kits chase height. AEV engineers for balance. Geometry Restored — Not Ignored - Heavy-duty radius arm drop brackets precisely lower the frame-side mounting points to restore proper caster and front suspension geometry. The result? Improved high-speed stability and predictable handling — even under load. Steering That Still Feels Right - A forged AEV Pitman Arm, paired with a robust frame-mounted track bar relocation bracket, keeps your steering angles correct and your axle centered. That means reduced bump steer, better tracking, and confidence whether you’re towing, commuting, or exploring. Dual-Rate Coils — Tuned for Your Engine - Unlike single-rate “lift-only” springs, AEV’s dual-rate front coil springs are tuned specifically for Super Duty axle weights and lift height. Separate spring rates for gas and diesel models ensure proper stance, controlled articulation, and ride comfort without sacrificing payload. Because capability shouldn’t disappear once you hook up a trailer. Engineered as a System The DualSport RT isn’t a box of parts — it’s a fully validated, integrated suspension package: AEV 4” Dual-Rate Front Coil Springs Bilstein 5100 Sh
