The ICON Vehicle Dynamics 2.5 Series Piggyback (PB) Front Shock Pair is a high-performance suspension upgrade for the 2005-2025 Ford F-250 and F-350 Super Duty 4WD. These shocks are custom-tuned to provide a smooth, controlled ride on the street and unmatched responsiveness in demanding off-road conditions. The piggyback reservoir design significantly increases oil volume to improve heat dissipation and prevent damping fade during prolonged use.

Features

• Vehicle Specific Valving: Configured specifically for the weight and suspension geometry of the Super Duty to ensure optimal handling.
• Internal Bump Zone: Features a 6061 billet aluminum manifold that creates an additional 20% of damping force as the shock reaches full compression, preventing harsh bottom-outs.
• Premium Construction: Utilizes one-piece impact-extruded aluminum cylinders for superior corrosion resistance and a 7/8-inch induction-hardened, chrome-plated shaft for extreme durability.
• Piggyback Reservoir: Increases oil capacity and cooling surface area, allowing the shock to maintain consistent performance under high-speed compression.
• Serviceable Design: 100% rebuildable and revalveable, allowing the shocks to be maintained or custom-tuned for specific vehicle setups.
• High-Quality Components: Equipped with PTFE-lined spherical bearings and application-specific mounting hardware for a precise, quiet fit.

Notes

• Specifically fits 2005-2025 Ford F-250 and F-350 Super Duty 4WD models.
• Designed for trucks with 2.5 inches of front suspension lift.
• Compatible with 0-3 inches of front lift on 2005-2019 models and varies slightly for 2020-2025 models depending on trim and Tremor packages.
• Not compatible with F-350 or F-450 Cab and Chassis models.
• Aftermarket wheels with lower offset or less backspace are recommended for proper clearance.
• Can be upgraded to the ICON Compression Damping Control Valve (CDCV) for 10 levels of user-adjustable damping.
