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!

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!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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!!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.
