Unleash the Full Potential of Your 4th Gen Ram’s Suspension

Upgrade your 2010–2013 Dodge Ram 2500 3500 (4th Gen) with the CORE 4X4 Long Arm Upgrade Kit, designed to provide superior strength, stability, and suspension travel. Factory short arms limit articulation, create a harsh ride, and reduce control under extreme conditions. Our true 4-link long arm design corrects suspension geometry, allowing smoother suspension cycling, better axle control, and a more comfortable ride. Whether you’re conquering rocky terrain or hauling heavy loads, this bolt-on kit enhances both on-road drivability and off-road capability.

Key Features and Benefits

  • True 4-Link Long Arm Design with Optimized Suspension Travel – Provides greater articulation and axle control while reducing harsh angles, improving handling and ride comfort. Unique upper arm bends enhance suspension movement and help maximize travel. For lifts under 3 inches, minor trimming of body mounts may be required for clearance.
  • Heavy-Duty Construction for Unmatched Durability – Crafted from high-strength DOM tubing (Upper arms: 1.75” OD, Lower arms: 2.25” OD) with Rock Jock Johnny Joints at both ends for maximum flexibility, adjustability, and longevity. Precision-cut 3/16” plate steel brackets provide a rock-solid foundation for extreme off-road use.
  • No Welding Required – Easy Installation with Body Mount Clearance Considerations – This 100% bolt-on kit seamlessly integrates with the factory crossmember for easy installation. While no welding is required, minor body mount trimming may be necessary for clearance on lifts under 3 inches.
  • Inward Bends for Large Tire Clearance Full Lift Compatibility – Designed to accommodate oversized tires while ensuring proper steering and suspension movement without interference. Fully adjustable to maintain proper geometry and recenter the axle for 0–6 inches of lift, with options available for lifts over 6 inches.

Enhanced Ride Quality, Stability, and Performance

Longer control arms create a smoother suspension arc, reducing harsh angles, wheel hop, and suspension bind. This results in better traction, improved comfort, and superior handling whether on the road or off.

Two-Stage Powder Coating for Maximum Durability

Every control arm and bracket undergoes a zinc primer base coat for superior corrosion resistance, followed by a top coat in your choice of 10 colors, ensuring long-term protection and a customized look.

Proudly Made in the USA

All components in our Long Arm Upgrade Kit are manufactured in our Orem, UT facility, with strict quality control to ensure maximum strength, reliability, and longevity.

Effortless Installation

Includes all necessary hardware for a hassle-free installation. With a 100% bolt-on design, there’s no welding required, making it an easy upgrade. For lifts under 3 inches, minor trimming of body mounts may be needed for clearance.


  • Vehicle Fitment: Dodge Ram 2500 3500 (2010-2013, 4th Gen) – Optimizes suspension geometry for improved axle control, enhanced stability, and superior handling, whether on rugged trails, hauling heavy loads, or cruising on the highway.

  • CORE Advantage: The true 4-link long arm design allows for greater suspension travel, reducing harsh angles and wheel hop, improving ride quality and handling under extreme conditions, and ensuring smoother articulation for better off-road performance.

  • Adjustability: Designed for lifts from 0 to 6 inches, this kit is fully adjustable, providing the ability to recenter the axle, accommodate larger tires, and maintain optimal suspension geometry for superior stability and handling.

  • Construction: Built with heavy-duty DOM tubing (upper arms: 1.75” OD, lower arms: 2.25” OD), Rock Jock Johnny Joints, and precision-cut 3/16” plate steel brackets, this kit delivers unmatched durability and flexibility for extreme off-road use and daily driving.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.
