King 25001-146A 2.5" Front Remote Reservoir Coilover Conversion Kit with Adjuster

The King Shocks 25001-146A is a 2.5-inch front remote reservoir coilover conversion kit with adjuster, purpose-built for Ford Super Duty 4WD trucks. This kit replaces the factory coil spring setup with a fully adjustable coilover shock system, delivering a significant upgrade in front suspension performance, ride quality, and ride height tunability.

King's OEM performance coilover conversion has been subjected to extensive dynamometer lab testing and real-world validation to develop optimal damping curves and spring rates for the Super Duty platform. Every component is manufactured to the same exacting tolerances found in King's high-end race shocks.

Key Features:

• 2.5" Diameter Shock Body: Larger shock body increases oil volume for cooler, more consistent damping performance under demanding conditions
• Remote Reservoir Design: External finned reservoir dramatically expands fluid capacity and heat dissipation, sustaining damping control under the most punishing use
• Adjustable Ride Height: Provides approximately 2" of front lift for a leveled stance; ride height can be further adjusted to suit lift kits or other ride height preferences
• Multiple Spring Rate Options: Adjustable spring rates available to match any application or load requirement
• Increased Wheel Travel: Improved suspension geometry for greater articulation and control
• Complete Conversion Kit: Includes everything needed to convert from a factory coil spring to a coilover shock system
• High-Strength 6061-T6 Aluminum Construction: Precision-machined components built for long-term durability
• Fully Rebuildable and Serviceable: Designed for ongoing maintenance, tuning, and long service life

The 25001-146A coilover conversion is an ideal upgrade for Ford F-250, F-350, F-450, and F-550 Super Duty owners looking to improve front-end ride quality, gain leveling lift, or build a platform compatible with aftermarket lift systems.
