Complete Front-End Solution for Maximum Performance

Upgrade your Dodge Ram 5500 (2008-2020) with our Adjustable Front Control Arm Set, designed to eliminate alignment issues, optimize suspension geometry, and enhance handling for heavy-duty applications. Whether you're towing, hauling, or off-roading, this complete front-end solution allows precise axle positioning, including pushing the front axle forward (“the stretch”) to fit larger tires without interference at the fender liner.

What's Included?

  • Adjustable Front Upper Control Arms (D-55-2008-FU2)
  • Adjustable Front Lower Control Arms (D-55-2008-FL2)

Key Features Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75" OD DOM steel tubing with .313" wall thickness, these control arms provide exceptional strength for heavy towing, hauling, and extreme off-road conditions.
  • Rock Jock Johnny Joints for Maximum Durability – Equipped with fully greaseable and rebuildable Rock Jock Johnny Joints, ensuring superior flexibility and long-lasting performance under extreme loads.
  • On-Vehicle Adjustability for Precision Alignment – Left-hand and right-hand threaded adjusters allow for fine-tuning caster and pinion angles without removal, ensuring perfect alignment correction for 0 to 6 inches of lift.
  • Optimized for Larger Tires Improved Steering Stability – Designed to push the front axle forward (“the stretch”), creating extra clearance for larger tires while maintaining proper caster angles for improved handling.

Recommended Pairing

Adjustable Front Track Bar (D-55-2008-FTB1) – For full front-end stability and steering precision, pair this set with the Adjustable Front Track Bar to eliminate bump steer and enhance steering control.

Optimized Suspension Performance

Our Adjustable Front Control Arm Set is a critical upgrade for restoring caster alignment, reducing wandering at highway speeds, and improving steering stability. Paired together, upper and lower control arms provide full axle recentering, reducing suspension stress and premature tire wear. For trucks used in towing and hauling, correcting caster angles is essential for maintaining stability and control under heavy loads.

Two-Stage Powder Coating

To ensure maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process. The first stage includes a zinc primer base coat, offering superior rust prevention and long-term protection. The second stage applies a durable top coat, available in 10 color options, allowing you to customize your suspension components while ensuring a long-lasting, high-quality finish.

Made in the USA

Proudly manufactured in Orem, UT, our control arms are built with American-sourced materials, ensuring strict quality control and superior reliability. Supporting American manufacturing means investing in premium craftsmanship and long-lasting performance for both 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 the Adjustable Front Control Arm Set means investing in better alignment, enhanced stability, and long-term durability. Pair this set with the Adjustable Front Track Bar (D-55-2008-FTB1) for a complete front suspension solution, improving handling, eliminating steering instability, and optimizing caster angles for a smoother ride and superior off-road capability. Upgrade today and experience the difference!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

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!!

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.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.
