Boost Performance and Control

Upgrade your Jeep Wrangler JL (2018-Present) with the Cruise Series Rear Lower Control Arms, designed to enhance durability, improve handling, and restore proper rear axle alignment. These control arms are a significant upgrade over factory components, offering improved strength, adjustability, and ride quality for both on-road stability and off-road flexibility.

Key Features and Benefits

  • Durable Steel Tubing Construction – Built from heavy-duty steel tubing, these control arms provide superior strength and long-lasting durability compared to factory components.
  • Precision Adjustability – Allows for accurate alignment correction and rear axle re-centering, accommodating lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Delivers a smoother ride, better articulation, and increased longevity over standard rubber bushings.
  • Improved Handling Ride Quality – Reduces rear-end instability and excessive suspension movement, enhancing both daily driving comfort and off-road capability.
  • Recommended Pairing for a Complete Suspension Solution – For full rear-end alignment control, pair with our Cruise Series Rear Upper Control Arms (CRS-J-JL-RU2).

Two-Stage Powder Coating for Maximum Protection

To maximize durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc Primer Base Coat – Provides a protective barrier against rust and environmental damage. Customizable Top Coat – Available in 10 color options, allowing you to personalize the look of your suspension components.

Made in the USA

Manufactured in Orem, UT, the Cruise Series Rear Lower Control Arms are built to the highest standards of American craftsmanship, ensuring superior durability and consistent, reliable performance in all driving conditions.

Optional Hardware Upgrade

Our Cruise Series Rear Lower Control Arms are designed for easy installation using factory hardware. However, for those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately to ensure a secure and hassle-free installation.

Upgrade today and experience the difference in ride quality, durability, and off-road control with CORE 4X4’s Cruise Series Rear Lower Control Arms!

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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. 👍👍
