Unleash the Full Potential of Your Dodge Ram’s Suspension

Upgrade your 2008–2009 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-35-2008-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.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.
