Fabtech K2145DL

2011–2016 Ford F350/F450 4WD 8-Lug

Part #: K2145DL

Overview

The Fabtech 6" Radius Arm System with Dirt Logic 4.0 Coilover & Rear DLSS is a high-performance suspension upgrade designed specifically for Ford F350 and F450 Super Duty trucks from 2011 to 2016. This comprehensive system enhances your vehicle's off-road capability, ride quality, and load-carrying capacity, making it ideal for heavy-duty applications, towing, and spirited off-road adventures.

Engineered for enthusiasts who demand maximum front suspension damping and durability, this system replaces the factory components with robust, precision-crafted parts. The result is improved wheel travel, better impact absorption, and a more controlled ride, whether you're navigating rugged trails or hauling heavy loads. With the Fabtech K2145DL, you'll experience superior handling, increased ground clearance, and enhanced stability under demanding conditions.

Key Features

The Fabtech K2145DL system incorporates advanced engineering and high-quality materials to deliver exceptional performance and longevity. Key features include:

• Heavy-duty upper coilover mounts constructed from 1.75" diameter DOM tubing, replacing factory coil spring mounts for increased strength and impact load distribution across the frame.
• Lower mounts made from 1/4" thick steel, providing solid attachment points to the axle housing for enhanced durability and stability.
• Stainless steel coilover conversion with Dirt Logic 4.0 shocks, offering superior damping performance and corrosion resistance for off-road and daily driving conditions.
• Radius arm design that maintains proper suspension geometry, ensuring precise steering and handling while accommodating larger tires and increased lift height.
• Impact load distribution across a wide section of the frame, reducing stress and extending component lifespan.
• Designed for easy bolt-on installation with minimal modifications required, allowing you to upgrade your suspension efficiently.
• Compatible with factory or aftermarket wheels and tires, providing flexibility for customization.
• Optimized for off-road use, supporting aggressive driving styles and challenging terrains.

Construction & Design

The Fabtech K2145DL system features a combination of high-strength steel and stainless steel components, ensuring durability and corrosion resistance in harsh environments. The upper coilover mounts are crafted from 1.75" diameter DOM tubing, which offers excellent strength-to-weight ratio and impact resistance. These mounts span across a broad section of the frame, effectively distributing impact loads and reducing stress concentrations.

The lower mounts are fabricated from 1/4" thick steel, providing a solid foundation for the coilover shocks and ensuring long-lasting performance. The radius arms are engineered to maintain proper suspension geometry, preventing caster and camber changes that can affect handling and tire wear. The entire system is designed with precision CAD modeling and TIG welding to ensure a perfect fit and reliable operation.

Performance & Sound

With the Dirt Logic 4.0 stainless steel coilover shocks, this system delivers exceptional damping control, improved ride quality, and increased wheel travel. The coilovers are engineered to handle heavy loads and off-road impacts, providing a smooth yet responsive ride. The system enhances your truck's off-road capability by allowing greater articulation and impact absorption, making it suitable for trail riding, rock crawling, or heavy-duty work.

Installation & Fitment

The Fabtech K2145DL is designed as a bolt-on upgrade, with most components fitting directly to the factory mounting points. The installation process typically requires basic hand tools and can be completed with standard mechanical skills. No cutting, drilling, or extensive modifications are necessary, although professional alignment is recommended after installation to ensure optimal handling and tire wear.

• Includes all necessary brackets, mounts, shocks, and hardware for a complete installation.
• Impact load distribution and frame reinforcement improve longevity and performance.
• Designed for 4WD models with 8-lug wheels, specifically for the 2011–2016 Ford F350 and F450 Super Duty trucks.
