Fabtech K2137DL

2011–2016 Ford F250 4WD

Part #: K2137DL

Overview

The Fabtech 6" Radius Arm System with DLSS 4.0 Coilover & Rear DLSS is a high-performance suspension upgrade designed specifically for Ford F250 4WD trucks from 2011 to 2016. This comprehensive system enhances your vehicle's off-road capability, ride quality, and load handling, making it an ideal choice for enthusiasts who demand maximum performance both on and off the pavement.

Built with durability and precision in mind, this kit replaces the factory suspension components with heavy-duty, stainless steel coilover conversions and radius arm upgrades. Whether you're tackling rugged trails, hauling heavy loads, or seeking improved stability and control, this system provides the strength and damping performance needed to elevate your Super Duty's capabilities.

Key Features

The Fabtech K2137DL system incorporates advanced engineering and premium materials to deliver superior suspension performance. Key features include:

• Heavy-duty upper coilover mounts constructed with 1.75" diameter DOM tubing, replacing factory coil spring mounts for enhanced impact load distribution and durability.
• Robust lower mounts made from 1/4" thick steel, securely attaching to the axle housing to provide solid mounting points for the Dirt Logic 4.0 stainless steel coilover piggyback reservoir shocks.
• Precision-designed radius arms that improve wheel alignment, caster, and camber, resulting in better handling and tire wear.
• Stainless steel coilover shocks with DLSS (Dual Load Support System) technology, offering adjustable damping and superior heat dissipation for consistent performance under demanding conditions.
• Impact-resistant components engineered to withstand off-road impacts and heavy loads, ensuring long-lasting performance and reliability.
• Impact load distribution across a wider frame section, reducing stress on individual components and enhancing overall suspension lifespan.
• Designed for easy bolt-on installation with minimal modifications required, allowing for a straightforward upgrade process.

Construction & Design

The Fabtech suspension system features high-quality stainless steel coilover shocks with a durable piggyback reservoir design, providing increased oil capacity and improved heat dissipation. The upper mounts utilize 1.75" DOM tubing, a material known for its strength and resistance to corrosion, ensuring longevity and consistent performance. The lower mounts are crafted from 1/4" steel, offering a sturdy foundation for the shocks and maintaining precise alignment.

The radius arms are engineered with a focus on impact load distribution, spanning a wide section of the frame to evenly spread forces during off-road driving. This design reduces stress on individual components and enhances the overall durability of the suspension system. The system's components are TIG-welded and CAD-designed for precise fitment and optimal strength, ensuring your vehicle maintains excellent handling characteristics and off-road capability.

Performance & Sound

This suspension upgrade significantly improves your Ford F250's front damping and overall ride quality. The Dirt Logic 4.0 shocks provide adjustable damping settings, allowing you to tailor the ride to your specific driving conditions. Expect improved wheel control, reduced body roll, and enhanced impact absorption over rough terrain. The upgraded suspension also supports increased load capacity, making it suitable for towing and heavy-duty applications.

Installation & Fitment

The Fabtech K2137DL system 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 may involve some disassembly of the existing suspension components. No cutting or welding is necessary, and the system is engineered for a straightforward installation that can be completed with standard mechanical skills.
