Designed for 2017-2022 Ford F250 and F350 4WD models, this Super Duty Coilover Conversion System is the perfect upgrade for owners looking to take their front suspension performance to the next level. This system allows the installation of Fabtech’s massive Dirt Logic 4.0 Remote Reservoir Coilover, the largest and most advanced coilover available for the Super Duty platform.
The Dirt Logic 4.0 coilover delivers an exceptional balance of ride comfort and off-road capability. It provides a smooth, controlled highway ride while maintaining the ability to absorb harsh impacts and tackle demanding off-road terrain with confidence.
This coilover conversion system utilizes the factory upper coil spring bucket and incorporates heavy-duty double shear mounting brackets. This design allows the Dirt Logic 4.0 to bolt directly into place without cutting or welding, creating a simple yet extremely strong mounting solution capable of handling punishing off-road conditions.
The Dirt Logic 4.0 coilover is constructed with a stainless steel shock body for maximum corrosion resistance in harsh environments. Surrounding the shock body is a dual-rate coil spring that delivers a progressive ride quality, providing comfort during normal driving while increasing resistance under aggressive suspension compression.
Each Dirt Logic 4.0 coilover has undergone extensive ride tuning to develop valving that delivers immediate performance benefits. The result is a suspension system that feels refined on the road while offering unmatched control and damping capability when navigating rough terrain.
This high-end coilover conversion system is the ultimate front suspension upgrade for Super Duty owners who demand premium performance, durability, and head-turning capability both on and off the road.
