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!


  • Vehicle Fitment: Designed for Ram 1500 09+, this rear control arm set enhances traction, eliminates wheel hop, and ensures precise axle alignment for daily driving, towing, and off-road use.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

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.

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.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.
