Superior Stability and Off-Road Performance

Maximize your Jeep Gladiator JT's performance with the Crawl Series Rear Lower Control Arms, designed for model years 2020-Present. These control arms enhance your off-road flexibility while maintaining impressive on-road stability. Engineered to combat common issues such as wheel hop and axle misalignment, they are the perfect solution for improved traction and handling.

Detailed Key Features and Benefits

  • Exceptional Strength and Durability – Built with 1.75″ OD DOM Tubing and a 5/16” wall thickness, these heavy-duty control arms are designed to outperform factory components, ensuring they withstand even the most demanding off-road conditions.
  • Enhanced Adjustability – Accommodates lifts from 0 to 6 inches, allowing for precise axle centering and alignment corrections to improve ride quality and stability.
  • Original Johnny Joints – Equipped with Johnny Joints at both ends for superior articulation, these control arms deliver unparalleled off-road flexibility without sacrificing durability.
  • Complete Rear Suspension Solution – Pair with our Rear Upper Control Arms for a fully dialed-in rear axle setup. Together, these components optimize pinion angles, improve axle centering, and eliminate issues like wheel hop for maximum traction and control.

Solving Rear-End Stability Challenges

The Crawl Series Rear Lower Control Arms address critical suspension deficiencies, such as wheel hop and misaligned axles, ensuring a smoother, more controlled ride. By providing precise adjustability and exceptional articulation, these arms allow your Jeep Gladiator JT to tackle uneven terrains and high-torque scenarios with ease, making them an essential upgrade for off-road enthusiasts.

Two-Stage Powder Coating

Each control arm undergoes a rigorous two-stage powder coating process. A zinc primer base provides a robust barrier against rust and environmental damage, while the top coat—available in 10 vibrant color options—offers a durable finish and a chance to customize your vehicle's appearance.

Made in the USA

Proudly manufactured in Orem, UT, our Crawl Series Rear Lower Control Arms represent the pinnacle of American craftsmanship. By sourcing materials locally and adhering to strict quality standards, we ensure every component exceeds expectations.

Optional Hardware Upgrade

Designed for seamless installation using factory hardware, these control arms make upgrading your suspension straightforward. Optional Grade 8 hardware kits are available for dealing with rusted or stubborn bolts.


  • Vehicle Fitment: Jeep Gladiator JT 20+ – Built for superior traction, articulation, and axle stability, these rear lower control arms enhance off-road flexibility while maintaining smooth and predictable handling on any terrain.

  • CORE Advantage: Designed to eliminate wheel hop, improve rear axle centering, and enhance traction, these control arms offer exceptional adjustability and articulation, ensuring precise suspension geometry for lifted and performance-driven setups.

  • Adjustability: Fully adjustable to accommodate lifts from 0 to 6 inches, these control arms allow fine-tuned axle positioning, pinion angle correction, and improved suspension dynamics to maximize both off-road capability and on-road comfort.

  • Construction: Crafted from 1.75” OD DOM tubing with a 5/16” wall thickness, these control arms feature Johnny Joints at both ends, providing extreme articulation, unmatched strength, and long-term durability for the toughest off-road conditions.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

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!!!!

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!
