Product Details

Unmatched Control for Maximum Stability Performance

Upgrade your Ram 1500 (2009–Present) with the Trail Series Fixed Rear Upper Control Arms, engineered for enhanced traction, axle stability, and improved ride comfort. Built to outperform factory components and competing aftermarket options, these control arms provide exceptional strength and suspension performance.

Whether you're towing, launching off the line, or tackling rugged terrain, this upgrade reduces wheel hop, eliminates axle deflection, and enhances power transfer, ensuring a more controlled and predictable driving experience.

Key Features Benefits

  • Built for Strength, Comfort Longevity – Constructed from high-strength steel tubing, these control arms feature a high-quality polyurethane bushing at one end and a Rock Jock Johnny Joint at the other, offering a perfect balance of articulation, durability, and NVH (Noise, Vibration, and Harshness) reduction.
  • 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 instability, especially under heavy loads or performance applications.
  • Superior Handling Predictable Steering Response – Enhances suspension geometry, minimizing unwanted flex, and improving cornering precision, braking stability, and towing control.
  • Recommended Pairing: For total rear axle stability, improved traction, and full suspension control, pair these upper control arms with the Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2).

Eliminate Wheel Hop Improve Ride Quality

Factory rubber bushings can create excessive preload on the axle, leading to wheel hop, instability, and inconsistent traction. The Trail Series Fixed Rear Upper Control Arms solve this by incorporating a hybrid joint design, allowing for free and controlled axle movement.

  • Johnny Joint – Delivers unmatched articulation and longevity.
  • Polyurethane Bushing – Effectively reduces NVH, making for a smoother, more stable ride.

When paired with our Trail Series Fixed Rear Lower Control Arms (TRL-R-15-2009-FXD-RL2), you gain full rear suspension control, ensuring your Ram 1500 stays planted, predictable, and responsive in any driving condition.

Highly Durable Two-Stage Powder Coating

Every Trail Series Control Arm undergoes a two-stage powder coating process for superior durability and corrosion resistance: Zinc primer base coat for maximum rust protection. Durable topcoat available in 10 color options to match your build.

Optional Hardware Upgrade

These control arms are designed for installation using factory hardware, but for added durability and a more secure fit, we offer an optional Grade 8 hardware kit (sold separately). This upgrade strengthens installation points and eliminates the risk of shifting under heavy loads.

Proudly Made in the USA

All CORE 4X4 components are designed, manufactured, and tested in Orem, UT, ensuring top-tier craftsmanship and strict quality control. Keeping production local allows us to maintain precise engineering standards, deliver industry-leading durability, and support American jobs.

Final Thoughts

The Trail Series Fixed Rear Upper Control Arms are an essential upgrade for Ram 1500 owners looking to eliminate wheel hop, improve ride quality, and enhance handling stability. With high-strength construction, reduced NVH, and superior suspension control, this upgrade delivers reliability and performance for any driving condition.

Upgrade today and experience the difference in traction, stability, and overall ride comfort!

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!

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 :) .

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

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.
