PSC BIG BORE XD DDS Steering System 18-26 Ford F-450/F-550

Take control of your Ford Superduty with the PSC BIG BORE XD DDS Steering System, engineered for trucks that carry serious weight, run oversized tires, or operate in demanding off-road and commercial environments. Factory steering can struggle to keep up with the added demands of lifted trucks, high-GVW conversions, and specialized work builds, leading to increased steering effort, unwanted wheel shake, and reduced driver confidence. This complete steering upgrade combines PSC’s BIG BORE XD steering gear with its Dynamic Damping Stabilizer (DDS) technology to improve steering response, reduce steering effort, and deliver greater stability behind the wheel. Whether you're building an adventure rig, outfitting a commercial truck, or upgrading a first responder vehicle, this system is designed to help your Super Duty handle heavy loads and challenging terrain with greater control. At the heart of the system is a BIG BORE XD steering gear featuring PSC-tuned valving, paired with the DDS through-shaft cylinder assist stabilizer to help manage unwanted steering movement and improve directional stability. The kit includes preassembled hydraulic hoses protected by high-temperature fire sleeves, a billet-aluminum Ultra Flow cylinder-assist tower, an integrated skid plate system, an offset bolt-on DDS clamp designed for the factory tie rod, and vehicle-specific mounting brackets and hardware. Designed for a 100% bolt-on installation, the system eliminates the need for custom welding and includes the primary components needed for installation. IMPORTANT INFO: A Dana 60 front axle is required, and fitment should be verified before ordering.
