2014–2018 Ram 2500 4WD

K3068

Overview:

The Fabtech 5-inch Radius Arm System is a comprehensive front suspension upgrade designed specifically for 2014 to 2018 Ram 2500 models. This system enhances the truck’s front suspension geometry to accommodate larger tires and lifted ride heights while maintaining factory ride quality and alignment specifications. Featuring replacement tubular radius arms with Fabtech’s exclusive dimple die side plates, this kit delivers superior strength and durability for demanding off-road and heavy-duty applications.

Ideal for Ram 2500 owners looking to improve suspension performance and clearance without compromising factory handling characteristics, this system includes coil spring spacers and Fabtech Performance Twin Tube shocks to ensure a smooth, controlled ride on and off the road.

Key Features:

The Fabtech 5-inch Radius Arm System offers a range of engineered enhancements to optimize suspension performance and durability:

• Replacement tubular radius arms with exclusive dimple die side plates for increased strength and rugged styling
• Increased caster angle to improve steering geometry for lifted trucks and oversized tires
• Angular steel coil spring spacers that retain the factory spring bow for proper alignment and ride quality
• Steel coil spring spacers in the rear to maintain the vehicle’s weight carrying capacity
• Heavy-duty 1/4" thick steel front and rear track bar drop brackets to center axles under the vehicle at new ride height
• Fabtech’s patented steel front bump stop extensions to prevent damage to springs and shocks, outperforming urethane bump stops
• Fabtech Performance Twin Tube shocks included for enhanced damping and ride control
• Designed to clear up to 37-inch tall tires with minor trimming
• No welding required; installation involves drilling 10 holes

Construction & Design:

Fabtech’s Radius Arm System is engineered with durability and performance in mind. The tubular radius arms are constructed from high-strength steel and feature Fabtech’s unique dimple die side plates, which increase structural integrity while providing a distinctive, aggressive appearance. The coil spring spacers are made from angular steel to preserve the factory spring bow, a critical design element that Chrysler incorporated to optimize alignment and ride comfort. This attention to detail ensures that the suspension upgrade does not sacrifice the truck’s original handling characteristics.

Steel track bar drop brackets and bump stop extensions are fabricated from heavy-duty steel to withstand the rigors of lifted suspension setups and off-road use. The inclusion of Fabtech’s Performance Twin Tube shocks complements the robust hardware with reliable damping performance tailored for lifted Ram 2500 trucks.

Installation & Fitment:

The Fabtech 5-inch Radius Arm System is designed for straightforward installation on 2014 to 2018 Ram 2500 4WD models, 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. Installation requires drilling 10 holes but no welding, making it accessible for experienced DIYers or professional installers. Estimated installation time is approximately 4.5 hours.

Minor trimming may be necessary to accommodate 37-inch tires on wheels ranging from 17x9 to 22x9.5 with a 5-inch backspacing.

What's Included:

• 5-inch tubular radius arms with dimple die side plates
• Angular steel front coil spring spacers
• Steel rear coil spring spacers
• Heavy-duty 1/4" thick steel front and rear track bar drop brackets
• Steel front bump stop extensions
• Fabtech Performance Twin Tube shocks
• All necessary hardware for installation

Ideal For:

This radius arm system is perfect for Ram 2500 owners who want to lift their trucks up to 5 inches while maintaining factory ride quality and alignment. It is especially suited for those running oversized tires up to 37 inches tall and seeking enhanced suspension strength and durability for off-road adventures, heavy towing, or daily driving with lifted suspension setups.

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.
