Unleash the Full Potential of Your Ram’s Suspension
Upgrade your 2010–2012 Dodge Ram 3500 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
- Optimized Suspension Travel True 4-Link Design – Longer control arms reduce suspension bind, creating a smoother ride, better axle control, and improved handling. The upper control arms feature inward bends for larger tire clearance and maximum articulation.
- Heavy-Duty DOM Tubing Precision-Steel Brackets – Built from 1.75” OD upper arms and 2.25” OD lower arms, paired with 3/16” precision-cut plate steel brackets for extreme durability. Rock Jock Johnny Joints at both ends provide maximum articulation, adjustability, and durability for off-road abuse.
- Fully Adjustable to Maintain Suspension Geometry – Compatible with 0–6 inches of lift, keeping the axle centered and suspension geometry correct. Options available for lifts over 6 inches upon request.
- Seamless Bolt-On Installation – No welding required, and integrates seamlessly with the existing factory crossmember. For lifts under 3 inches, minor trimming of body mounts may be necessary for clearance.
Recommended Pairing for a Complete Front-End Solution
Adjustable Front Track Bar – D-35-2010-FTB1 ensures proper front axle alignment and eliminates steering instability when paired with the long arm kit.
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.
