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.

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.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

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 :) .

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.
