Engineered To Handle The Roughest Roads With Ease

The Rock Krawler F2AS4005-RR suspension system is a complete performance upgrade tailored for diesel-powered 2017–2022 Ford F-250 and F-350 4WD models. At the core of the system are sport-tuned triple-rate front coils that manage weight, improve stability, and respond progressively to changing terrain. A set of RR 2.625" remote reservoir shocks for both the front and rear helps manage heat and shock fade, especially during extended off-road use. The kit also includes control arm drop brackets, an adjustable front sway bar link set, a track bar drop bracket, and a drop pitman arm, all working together to correct steering geometry and maintain proper axle alignment after the lift. Extended front brake lines and bump stop extensions ensure full travel and safe operation without overstressing stock components. Rear U-bolt assemblies provide secure lift retention, and the entire system installs with bolt-on hardware for ease and reliability. Whether you're fine-tuning your build or starting fresh, this system offers a refined balance of performance and ride quality in one robust package.
