Unmatched Control for Maximum Stability Performance

Upgrade your Ram 1500 (2009–Present) with the Trail Series Fixed Rear Upper Control Arms, engineered for enhanced traction, axle stability, and improved ride comfort. Built to outperform factory components and competing aftermarket options, these control arms provide exceptional strength and suspension performance.

Whether you're towing, launching off the line, or tackling rugged terrain, this upgrade reduces wheel hop, eliminates axle deflection, and enhances power transfer, ensuring a more controlled and predictable driving experience.

Key Features Benefits

  • Built for Strength, Comfort Longevity – Constructed from high-strength steel tubing, these control arms feature a high-quality polyurethane bushing at one end and a Rock Jock Johnny Joint at the other, offering a perfect balance of articulation, durability, and NVH (Noise, Vibration, and Harshness) reduction.
  • Factory-Length Design for Seamless Fit – Designed to match OEM control arm length, making them a direct replacement for factory arms, ideal for stock, leveled, or lowered setups (up to 2” drop).
  • Eliminates Wheel Hop Maximizes Traction – Reduces axle movement under acceleration, preventing loss of traction and instability, especially under heavy loads or performance applications.
  • Superior Handling Predictable Steering Response – Enhances suspension geometry, minimizing unwanted flex, and improving cornering precision, braking stability, and towing control.
  • Recommended Pairing: For total rear axle stability, improved traction, and full suspension control, pair these upper control arms with the Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2).

Eliminate Wheel Hop Improve Ride Quality

Factory rubber bushings can create excessive preload on the axle, leading to wheel hop, instability, and inconsistent traction. The Trail Series Fixed Rear Upper Control Arms solve this by incorporating a hybrid joint design, allowing for free and controlled axle movement.

  • Johnny Joint – Delivers unmatched articulation and longevity.
  • Polyurethane Bushing – Effectively reduces NVH, making for a smoother, more stable ride.

When paired with our Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2), you gain full rear suspension control, ensuring your Ram 1500 stays planted, predictable, and responsive in any driving condition.

Highly Durable Two-Stage Powder Coating

Every Trail Series Control Arm undergoes a two-stage powder coating process for superior durability and corrosion resistance: Zinc primer base coat for maximum rust protection. Durable topcoat available in 10 color options to match your build.

Proudly Made in the USA

All CORE 4X4 components are designed, manufactured, and tested in Orem, UT, ensuring top-tier craftsmanship and strict quality control. Keeping production local allows us to maintain precise engineering standards, deliver industry-leading durability, and support American jobs.

Final Thoughts

The Trail Series Fixed Rear Upper Control Arms are an essential upgrade for Ram 1500 owners looking to eliminate wheel hop, improve ride quality, and enhance handling stability. With high-strength construction, reduced NVH, and superior suspension control, this upgrade delivers reliability and performance for any driving condition.

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 wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

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.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

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!!
