This complete 4.5-inch lift system combines heavy-duty remote-reservoir shocks with factory-replacement radius arms to deliver stable towing performance and permanent ground clearance.

Engineered exclusively for the 2023 and newer Ford F-250 and F-350 diesel platforms, this Stage 5 suspension package replaces worn factory geometry with purpose-tuned components that eliminate bump steer and restore predictable handling under load.

• CNC-machined 6061-T6 aluminum shock bodies and twin expansion packs provide rapid heat dissipation and consistent damping during long-haul highway driving or continuous trail articulation.
• Hardened steel radius arms feature direct-factory mounting points to resolve the alignment shifts and tire wear typical of drop-spacer lifts, requiring no cutting, welding, or bracket modification.
• Precision-calibrated valving absorbs road harshness rather than transmitting it to the cabin, solving the stiff, bouncy ride quality most aftermarket systems introduce on heavily cabbed dually chassis.
• Pre-charged nitrogen reservoirs maintain constant spring tension and suspension travel, reliably supporting payloads exceeding 10,000 pounds on the front axle without sag or bottoming out.
• Specially tuned damping profiles target the high torque and curb weight of factory diesel engines, controlling brake dive and drive-line squat without sacrificing fuel economy.
• A lifetime limited warranty covers manufacturing defects in the shock casings, seals, and remote reservoirs, protecting your investment against premature fatigue or fluid loss.
