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!

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

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.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .
