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.

  • 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.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

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!

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!
