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.
