Superior Strength, Maximum Clearance, and Unmatched Durability
Upgrade your 2014-Present Ram 2500 with the CORE 4X4 Heavy-Duty Radius Arms, a massive improvement over weak factory-stamped steel arms. Designed for lifted trucks (3” and above), these radius arms increase wheelbase, improve caster adjustability, and enhance suspension articulation. Built from fully boxed, internally gusseted 3/16” plate steel, these arms are engineered to withstand extreme off-road abuse while delivering superior on-road comfort. With an inward bend design, these arms increase tire clearance, allowing for 37” tires at factory offset with no rubbing and up to 40” tires with additional modifications. Equipped with massive 3” Rock Jock Johnny Joints, these arms provide a greater range of motion, smoother ride quality, and better handling in all conditions.
Key Features and Benefits
- Fully boxed 3/16” plate steel construction – Enclosed and internally gusseted for extreme strength, protection from debris, and long-term durability.
- Massive 3” Rock Jock Johnny Joints – Upgraded from factory bushings for better articulation, smoother ride quality, and increased strength.
- Inset design for maximum tire clearance – Allows 37” tires at factory offset and up to 40” tires with additional modifications.
- Optimized for lifted trucks (3” and above) – Extends wheelbase and improves caster adjustment to dial in alignment at lifted heights.
- Integrated limiting strap mounts – Ensures suspension stays within safe travel limits, preventing overextension damage in extreme conditions.
The Ultimate Upgrade for Strength and Handling
Factory radius arms are prone to flex, lack adjustability, and severely limit tire clearance. CORE 4X4 Radius Arms eliminate these issues, giving your Ram 2500 a planted, stable ride and maximum control over rough terrain. The addition of Rock Jock Johnny Joints drastically improves suspension articulation and ride smoothness, making these the ideal solution for off-road enthusiasts and heavy-duty truck owners alike. For lifted trucks, these arms restore proper suspension geometry, helping eliminate wandering steering, poor caster angles, and excessive tire wear. With the ability to push your front axle forward, they also ensure proper tire fitment without fender liner interference.
Two-Stage Powder Coating for Maximum Durability
To protect against corrosion, rust, and harsh terrain, all radius arms undergo a two-stage powder coating process. A zinc primer base coat provides superior rust prevention, while the top coat, available in 10 colors, enhances durability and style.
Proudly Made in the USA
Manufactured in Orem, UT, using premium American-sourced materials, these CORE 4X4 Radius Arms are built to exceed industry standards. Supporting American manufacturing means investing in superior craftsmanship, quality, and long-lasting performance.
Straightforward Installation
Designed for bolt-on installation, these arms mount to factory locations and include pre-welded mounting brackets. If dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a hassle-free installation.
Power Wagon Fitment
These radius arms will fit the Ram Power Wagon, but due to the factory sway bar disconnect system, some articulation will be limited. However, they still provide enhanced ride quality, handling, and durability, making them a valuable upgrade for Power Wagon owners seeking improved on-road manners and strength.

Whether you're towing, hauling, or hitting extreme off-road trails, these arms deliver unmatched performance, better ride quality, and extreme durability.
