Unmatched Performance Control for Any Driving Condition

Upgrade your Ram 1500 (2009–Present) with the Track Series Fixed Rear Control Arm Set, the ultimate solution for eliminating wheel hop, improving traction, and ensuring precise axle control. Engineered to outperform factory components and competing aftermarket options, this set provides exceptional durability, stability, and handling whether you're daily driving, towing, off-roading, or pushing your truck to the limit at the track.

What’s Included in the Set?

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

Key Features Benefits

  • Built for Maximum Strength Longevity – Constructed from heavy-duty steel tubing and featuring Rock Jock Johnny Joints at both ends, these control arms provide unrivaled articulation, durability, and suspension performance.
  • 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 improving stability, especially under load or in performance applications.
  • Superior Handling Predictable Steering Response – Enhances suspension geometry, reducing unwanted flex and improving cornering precision, braking stability, and towing control.

Total Rear Suspension Control

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

Eliminate Wheel Hop for Maximum Power Transfer

Wheel hop occurs when the axle binds and oscillates under load, often caused by factory rubber bushings that create excess preload on the suspension. This uncontrolled movement reduces traction and puts unnecessary strain on suspension components.

The Track Series Fixed Rear Control Arm Set solves this by utilizing Rock Jock Johnny Joints at both ends, allowing free and independent axle movement without the restriction of rubber bushings. This ensures consistent tire contact with the road, eliminates axle wrap, and significantly improves acceleration stability.

Highly Durable Two-Stage Powder Coating

Every Track Series Control Arm undergoes a two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat provides advanced rust protection, followed by a durable topcoat available in 10 color options to match your build.

Optional Hardware Upgrade

This control arm set is designed to be installed using factory hardware, but for enhanced durability and a more secure installation, we offer an optional Grade 8 hardware kit (sold separately). This upgrade provides a stronger, more reliable connection, reducing the risk of unwanted shifting under heavy loads.

Proudly Made in the USA

All CORE 4X4 components are designed, manufactured, and tested in Orem, UT, ensuring strict quality control and premium craftsmanship. By keeping production local, we maintain full oversight of material sourcing, welding, machining, and finishing, guaranteeing industry-leading durability and precision engineering.

Final Thoughts

The Track Series Fixed Rear Control Arm Set is the ultimate upgrade for Ram 1500 owners looking for superior axle control, maximum traction, and long-lasting durability. Whether you’re eliminating wheel hop, improving towing stability, or enhancing handling, this set is engineered to keep your truck planted and performing at its best. Upgrade today and experience the difference in traction, stability, and control!

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

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 broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

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.
