Performance, Strength, and Stability

Upgrade your Dodge Ram 4500 (2008-2020) with our Adjustable Front Upper Control Arms, designed to refine caster and pinion angles for improved handling, ride quality, and suspension durability. When lifting your truck, improper caster angles can lead to wandering steering, rough tracking, and instability—our control arms correct these issues, restoring confident handling on and off the road.

Built specifically for heavy-duty applications, these control arms are engineered for towing, hauling, and commercial-use trucks, providing exceptional strength without compromising ride comfort. When paired with our Adjustable Front Lower Control Arms, they allow for precise axle positioning, including pushing the front axle forward (commonly referred to as “the stretch”), enabling larger tire fitment without fender liner interference.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75" OD DOM steel tubing with .313" wall thickness, ensuring extreme strength for heavy towing and off-road durability.
  • Rock Jock Johnny Joints for Maximum Durability – Equipped with fully greaseable and rebuildable Rock Jock Johnny Joints, providing exceptional wear resistance and long-term reliability under heavy loads.
  • On-Vehicle Adjustability for Precision Alignment – Left-hand and right-hand threaded adjusters allow for fine-tuning caster and pinion angle without removal, ensuring perfect alignment correction for 0 to 6 inches of lift.
  • Optimized for Larger Tires Improved Steering Stability – Allows for pushing the front axle forward (“the stretch”) to run larger tires without rubbing the rear of the fender liner, improving clearance and functionality.
  • Recommended Pairing – For complete front-end alignment and suspension control, pair with Adjustable Front Lower Control Arms (D-45-2008-FL2) for full axle recentering, optimal caster correction, and enhanced tire clearance.

Optimized Suspension Performance

Our Adjustable Front Upper Control Arms play a crucial role in restoring caster alignment, eliminating wandering at highway speeds, and improving steering response. When paired with Front Lower Control Arms, they allow for full axle recentering, reducing stress on suspension components and enhancing overall ride comfort and stability.

For lifted trucks used in towing and hauling, proper caster correction significantly improves handling under load, preventing excessive front-end drift or tire wear.

Two-Stage Powder Coating

To maximize durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat – Provides superior rust prevention. Durable top coat – Available in 10 colors to match your truck’s aesthetics while ensuring long-lasting protection.

Made in the USA

Manufactured in Orem, UT, our control arms are built with American-sourced materials, ensuring rigorous quality control and unmatched reliability. Supporting American manufacturing means investing in superior craftsmanship and long-lasting performance for work and off-road applications.

Optional Hardware Upgrade

These control arms install using factory hardware, but for rusted or stubborn bolts, we offer Grade 8 hardware kits, available separately, for a hassle-free installation.

Upgrade today and experience the difference!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

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.
