Key Features

The Fabtech Dirt Logic 4.0 Coilover Conversion System incorporates several advanced features designed to optimize your vehicle's suspension performance:

• Constructed with 1.75" diameter DOM tubing for the upper coilover mounts, replacing factory coil spring mounts with a robust, impact-resistant design that spans across a wide section of the frame for superior load distribution.
• Lower mounts are fabricated from 1/4" thick steel, providing solid attachment points to the axle housing, ensuring durability and stability during heavy-duty use.
• Stainless steel coilover shocks with piggyback reservoirs deliver consistent damping performance, improved heat dissipation, and enhanced ride quality over stock components.
• Designed to support maximum front suspension damping, helping to maintain control and comfort during off-road excursions or when carrying heavy loads.
• Engineered with precision to ensure proper alignment and fitment, reducing installation time and ensuring reliable operation.
• Heavy-duty impact load distribution across the frame helps prevent damage and prolongs suspension component lifespan.
• Compatible with a wide range of Ford Super Duty models from 2011 to 2016, making it a versatile upgrade for your truck.

Construction & Design

The system features high-grade stainless steel for the coilover shocks, ensuring corrosion resistance and long-lasting performance in harsh environments. The upper mounts are crafted from 1.75" diameter DOM tubing, a material known for its strength and durability, providing a solid foundation for the coilover assembly. The lower mounts are made from 1/4" thick steel, offering a robust connection point to the axle housing. All components are TIG-welded and precisely engineered to ensure a perfect fit and optimal performance. The design emphasizes impact load distribution, heat dissipation, and ease of installation, making it a reliable upgrade for demanding applications.

Performance & Sound

With the Dirt Logic 4.0 coilover conversion system, you will experience significantly improved front suspension damping, resulting in better handling, reduced body roll, and enhanced ride comfort. The piggyback reservoir shocks help manage heat buildup during extended off-road use, maintaining consistent damping performance. While specific horsepower or torque gains are not claimed, the upgraded suspension provides better control and stability, especially when navigating rough terrain or carrying heavy loads. The system also offers a noticeable improvement in ride quality and responsiveness compared to factory components.

Installation & Fitment

The Fabtech Dirt Logic 4.0 Coilover Conversion System is designed as a bolt-on upgrade for your Ford F250, F350, F450, or F550 4WD trucks from 2011 to 2016. The installation process involves replacing the factory coil spring mounts with the new upper coilover mounts and attaching the stainless steel shocks to the existing axle and frame points. No cutting, drilling, or extensive modifications are typically required, and the system is engineered for straightforward installation with standard hand tools. Proper alignment and torque specifications should be followed to ensure optimal performance and safety.
