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.

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👌🏽

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!

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.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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.
