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.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

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 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.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

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!
