Superior Strength, Maximum Clearance, and Unmatched Durability

Upgrade your 2013-Present Ram 3500 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.

What’s Included?

  • CORE 4X4 Heavy-Duty Radius Arms (R-35-2013-RDA2)
  • Integrated Limiting Strap Mounts
  • Pre-Welded Factory Bracket Mounting Points

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 3500 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.

Final Thoughts

The CORE 4X4 Radius Arms for Ram 3500 are the ultimate upgrade for improved handling, maximum strength, and superior tire clearance. Whether you're towing, hauling, or hitting extreme off-road trails, these arms deliver unmatched performance, better ride quality, and extreme durability. Upgrade today and experience the CORE 4X4 difference!

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.
