Unmatched Rear Suspension Control

Upgrade your Ram 1500 (2009–Present) with the Trail Series Adjustable Rear Control Arm Set, engineered to eliminate wheel hop, enhance traction, and provide precise axle alignment. Designed for daily drivers, off-road enthusiasts, and towing applications, this set ensures your rear suspension operates at peak performance, no matter the terrain.

Key Features Benefits

  • Heavy-duty DOM tubing construction – Built from 1.75" OD, .313" wall DOM tubing for maximum strength and durability.
  • Polyurethane Johnny Joint combo – Features high-grade polyurethane bushings at the fixed ends for reduced NVH (Noise, Vibration, and Harshness) and RockJock Johnny Joints at the adjustable ends for maximum articulation and flexibility.
  • Full adjustability for optimal suspension control – Designed to fine-tune rear axle positioning for pinion angle correction, improved traction, and a smoother ride.
  • Recommended pairing – For total rear-end stability and complete axle alignment, pair with the Trail Series Adjustable Rear Panhard Track Bar (TRL-R-15-2009-RPTB1) to ensure precise suspension geometry and eliminate lateral axle shift.

Eliminate Wheel Hop Maintain Axle Stability

Factory control arms allow unwanted axle movement, leading to wheel hop, traction loss, and uneven tire wear. By replacing them with fully adjustable upper and lower control arms, you gain control over axle positioning, ensuring power is transferred efficiently to the ground. Pairing these arms with an adjustable track bar optimizes suspension geometry, creating a balanced, high-performance rear end.

Highly Durable Two-Stage Powder Coating

All components undergo a two-stage powder coating process for maximum durability and corrosion resistance. The zinc primer base coat provides superior rust protection, while the durable topcoat is available in 10 color options for a customized look.

Optional Hardware Upgrade

This control arm set is designed for installation using factory hardware, but for enhanced durability and a more secure installation, we offer an optional Grade 8 hardware kit (sold separately).

Proudly Made in the USA

Manufactured in Orem, UT, every CORE 4X4 component meets strict quality control standards for precision, strength, and long-term durability.

Final Thoughts

The Trail Series Adjustable Rear Control Arm Set is a must-have upgrade for Ram 1500 owners looking for improved suspension performance, better handling, and enhanced stability. By combining adjustable control arms with an adjustable track bar, you gain complete control over axle positioning, ensuring your truck stays planted in all driving conditions. Upgrade today and experience the difference in traction, handling, and suspension control!

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!!

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

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!!
