Performance, Strength, and Stability

Upgrade your Dodge Ram 5500 (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.

What’s Included in the Kit?

  • Adjustable Front Upper Control Arms (D-55-2008-FU2)

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-55-2008-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.

In Conclusion

Upgrading to Adjustable Front Upper Control Arms means investing in better alignment, enhanced stability, and long-term durability. Pair them with Front Lower Control Arms for a complete front suspension upgrade, improving handling, eliminating steering instability, and optimizing caster for a smoother ride and superior off-road capability.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!
