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.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

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.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

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.
