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.

What’s Included in the Kit?

  • Adjustable Front Upper Control Arms (D-45-2008-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-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.

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 couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

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.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

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.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
