Fabtech 5in Radius Arm System with Coil Spacers and Dirt Logic Shocks

2014–2018 Ram 2500 4WD

K3069DL

Overview:

The Fabtech 5-inch Radius Arm System with Coil Spacers and Dirt Logic Stainless Steel Shocks is engineered to enhance the front suspension of the 2014 to 2018 Ram 2500 models. Designed for enthusiasts seeking improved off-road capability and lifted suspension performance, this system replaces the factory radius arms with heavy-duty tubular components that increase caster angle, optimizing handling and tire clearance for oversized tires up to 37 inches tall. The inclusion of coil spacers preserves the factory spring bow, maintaining Chrysler’s intended alignment and ride quality, while the Dirt Logic shocks provide superior damping for both on- and off-road conditions.

This comprehensive suspension upgrade is ideal for Ram 2500 owners who demand rugged durability, enhanced suspension geometry, and the ability to run larger tires without compromising vehicle stability or comfort.

Key Features:

The Fabtech 5in Radius Arm System combines innovative engineering and robust materials to deliver a reliable lift solution. Key features include:

• Replacement tubular radius arms with exclusive dimple die side plates for increased strength and a distinctive rugged look
• Increased caster angle to improve steering geometry and accommodate oversized tires and lifted suspension heights
• Angular steel coil spacers for the front springs that retain the factory spring bow, preserving Chrysler’s unique alignment specifications and ride quality
• Steel coil spacers for the rear springs to maintain the vehicle’s weight carrying capacity
• Heavy-duty 1/4-inch thick steel front and rear track bar drop brackets to center the axles under the vehicle at the new ride height
• Fabtech’s patented steel front bump stop extensions that prevent damage to springs and shocks, outperforming urethane bump stops found in other kits
• Front and rear 2.25-inch Dirt Logic Stainless Steel shocks designed for enhanced durability and performance
• Clearance for tires up to 37 inches tall with minor trimming required depending on wheel size
• No welding required; installation involves drilling 10 holes with an estimated time of 4.5 hours

Construction & Design:

Fabtech’s 5-inch Radius Arm System is crafted from high-strength tubular steel, featuring dimple die side plates that add rigidity and a visually aggressive style. The coil spacers are precision-formed from angular steel to maintain the factory spring bow, a critical design element that supports proper alignment and ride comfort. The track bar drop brackets are constructed from 1/4-inch thick steel, ensuring durability and precise axle positioning after lift installation. The front bump stop extensions are fabricated from steel, providing a robust solution that eliminates the risk of damage common with urethane alternatives. The Dirt Logic shocks are stainless steel-bodied, offering corrosion resistance and consistent damping performance in demanding environments.

Installation & Fitment:

This system is designed for straightforward installation with no welding required. The process involves drilling 10 holes and minor trimming of the wheel wells depending on tire and wheel size. The kit supports a variety of tire and wheel combinations, including 37x12.50R17, 37x12.50R18, 37x13.50R20, and 37x13.50R22 tires with corresponding wheel widths and backspacing, requiring only minor trimming for clearance.

Fitment covers a wide range of Ram 2500 models from 2014 through 2018, including Big Horn, Laramie, Laramie Limited (2014–2015), Laramie Longhorn, Limited (2016–2018), Lone Star (2014–2015), Outdoorsman (2014–2016), Power Wagon, SLT, and Tradesman trims.

What's Included:

• Front and rear tubular radius arms with dimple die side plates
• Front and rear coil spring spacers (angular steel for front, steel for rear)
• Front and rear 2.25-inch Dirt Logic Stainless Steel shocks
• Heavy-duty 1/4-inch thick steel front and rear track bar drop brackets
• Steel front bump stop extensions
• All necessary hardware for installation

Ideal For:

This Fabtech Radius Arm System is perfect for Ram 2500 owners who want to lift their trucks by 5 inches while maintaining factory ride quality and alignment. It is especially suited for off-road enthusiasts who require clearance for large 37-inch tires and enhanced suspension geometry for improved handling. The system also benefits those who prioritize durability and long-term reliability with heavy-duty components designed to withstand harsh conditions and demanding use.

Fabtech is an off-road suspension leader producing lift kits, shocks, and related components to increase ride height, clear larger tires, and improve capability. Their systems are engineered for specific trucks and SUVs, blending on-road drivability with the added travel and strength enthusiasts want for trails, desert runs, and overland builds.
