The RK Suspension 4.0" Lift Height X-Factor System for the Ford Super Duty is expertly engineered to elevate both ride quality and performance, making it the ultimate upgrade for your everyday workhorse or adventure vehicle. Every component is precision-crafted in-house to optimize factory geometry, ensuring enhanced off-road stability for those who crave the thrill of the trail. It all starts with the tuned multi rate coils. Then we enhance them with our 4 Link geometry that provides improved axle control, removes suspension bind found in conventional radius arm systems, and allows for much smoother articulation off road. But we also understand that your truck isn’t just for play—it’s a workhorse. Whether you're navigating city streets, conquering rugged terrain, or towing heavy loads, RK Suspension delivers the reliability, strength, and performance needed to tackle any challenge with confidence!
