Enhanced Stability Control for Any Driving Condition

Upgrade your Ram 1500 (2009–Present) with the Trail Series Fixed Rear Control Arm Set, designed to eliminate wheel hop, improve traction, and enhance overall ride quality. Built to outperform factory components and competing aftermarket options, this set delivers exceptional durability, handling, and stability whether you're daily driving, towing, off-roading, or putting power to the pavement.

What’s Included in the Set?

  • Trail Series Fixed Rear Upper Control Arms (TRL-R-15-2009-FXD-RU2)
  • Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2)

Key Features Benefits

  • Durable Hybrid Joint Design for Strength Comfort – Built with high-strength steel tubing, these control arms feature a high-quality polyurethane bushing at one end and a RockJock Johnny Joint at the other. This combination provides optimal articulation, durability, and reduced NVH (Noise, Vibration, and Harshness).
  • Factory-Length Design for Seamless Fit – Matches OEM control arm length, making it a direct replacement for factory arms, perfect 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.

Total Rear Suspension Control

For maximum axle stability and precise rear-end positioning, we recommend pairing this set with the Trail Series Fixed Rear Panhard Track Bar (TRL-R-15-2009-FXD-RPTB1).

Eliminate Wheel Hop Improve Ride Comfort

Factory rubber bushings can bind under load, creating excessive preload on the suspension, which leads to axle oscillation (wheel hop), reduced traction, and unpredictable handling. The Trail Series Fixed Rear Control Arm Set solves this by utilizing a combination of polyurethane bushings and Johnny Joints, allowing free and controlled axle movement.

Polyurethane bushings effectively reduce NVH, ensuring a quieter, smoother ride while maintaining firm axle control. Johnny Joints allow for increased articulation and longevity, eliminating axle wrap and providing improved traction and acceleration stability.

When paired with our Trail Series Fixed Rear Panhard Track Bar (TRL-R-15-2009-FXD-RPTB1), you get full rear suspension control, keeping your truck planted and predictable 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. A zinc primer base coat provides maximum rust protection, while the durable topcoat is available in 10 color options to match your build.

Optional Hardware Upgrade

This control arm set is designed for installation using factory hardware, but for added durability and a more secure fit, we offer an optional Grade 8 hardware kit (sold separately). This upgrade strengthens installation points and eliminates the risk of shifting under heavy loads.

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 Control Arm Set is the ideal upgrade for Ram 1500 owners looking to eliminate wheel hop, improve ride comfort, and enhance handling stability. With high-strength construction, reduced NVH, and superior suspension control, this set delivers reliability and performance for any driving condition. Upgrade today and experience the difference in traction, stability, and overall ride comfort!

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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

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!

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

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!!

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!
