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 have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.
