Enhanced Performance and Control

Upgrade your Jeep Gladiator JT (2020-Present) with our Cruise Series Rear Control Arm Set, designed to provide superior handling, durability, and axle alignment correction. This set includes both rear upper and rear lower control arms, working together to re-center the rear axle and correct pinion angles, ensuring a smoother, more controlled driving experience both on and off-road.

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built from high-strength steel tubing for maximum durability and impact resistance.
  • Adjustable for 0 to 6 Inches of Lift – Allows for precise pinion angle correction and axle re-centering after lifting your Gladiator.
  • Tapered Polyurethane Bushings – Absorb vibration and enhance responsiveness, providing a smoother ride than stock rubber bushings.
  • Complete Rear Axle Alignment Solution – When paired with our Cruise Series Rear Track Bar (CRS-J-JT-RTB1), this set provides full control over rear suspension geometry, eliminating driveline vibrations and rear-end instability.

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for maximum corrosion resistance and long-lasting durability. Zinc primer base coat ensures protection from rust and environmental wear. Top coat available in 10 color options, allowing for customization to match your vehicle’s build.

Proudly Made in the USA

Manufactured in Orem, UT, our Cruise Series Rear Control Arm Set is built to strict quality standards, ensuring reliability, strength, and superior performance.

Optional Hardware Upgrade

  • The Cruise Series Rear Control Arms install using factory hardware.
  • For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately to simplify installation.

Upgrade today and take full control over your Jeep’s rear suspension with the strength and precision of CORE 4X4’s industry-leading components!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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!

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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

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)

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.
