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.

 

  • Vehicle Fitment: Dodge Ram 3500 10-12 Designed to improve suspension travel, enhance axle control, and provide superior handling for both on-road comfort and off-road capability, making your truck more versatile under any load or terrain.

  • CORE Advantage: The true 4-link long arm design reduces suspension bind, creating smoother cycling, better axle control, and improved ride comfort. Inward bends on the upper arms increase articulation and clearance for larger tires, improving overall suspension performance.

  • Adjustability: Fully adjustable to accommodate 0-6 inches of lift, keeping suspension geometry correct and axle centering precise. Custom options are available for lifts over 6 inches to ensure optimal performance and handling for any setup.

  • Construction: Heavy-duty DOM tubing (1.75” OD upper, 2.25” OD lower) and 3/16” plate steel brackets ensure exceptional strength and durability. Rock Jock Johnny Joints provide maximum articulation, adjustability, and reliability for extreme off-road use.

  • 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.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

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.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.
