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!

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

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.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

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!

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.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

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
