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.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

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!!
