Features
Upgrade your Ford F-350’s rear suspension with the RAS HD Suspension Kit—designed specifically for 2011–2025 models without factory overload springs. This bolt-on RoadActive Suspension system strengthens your rear leaf springs by 30–40%, reducing squat, sway, and bounce while providing a smoother, more stable ride under load or unloaded.
Unlike air bag systems, RAS is fully mechanical and maintenance-free—no compressors, air lines, leaks, or constant adjustments are required. The included heavy-duty helper springs stabilize your truck for towing and hauling while maintaining or improving stock unloaded ride quality. Each kit ships fully assembled and is ready for fast, bolt-on installation.
Key Features:
• Fits 2011–2025 Ford F-350 trucks without factory overload springs
• Strengthens rear leaf springs by 30–40% for added support
• Includes RAS Heavy Duty Helper Springs for each rear leaf spring
• Reduces rear-end squat, body roll, bounce, and axle wrap
• Progressive load support for towing and hauling
• Maintenance-free—no air lines, leaks, or adjustments needed
• Fully assembled for fast, bolt-on installation (~45–60 minutes)
• Same-as or better-than stock unloaded ride quality
