Complete Rear-End Suspension Control

Upgrade your Jeep Wrangler JL (2018-Present) with the Cruise Series Rear Control Arm Set, engineered to restore alignment, re-center the rear axle, and eliminate driveline vibrations caused by improper pinion angles.

This comprehensive rear-end solution replaces weak factory components with stronger, adjustable control arms, ensuring on-road stability and off-road durability.

Key Features and Benefits

  • Heavy-Duty Steel Tubing Construction – Built for maximum strength and durability, ensuring your suspension can handle the toughest conditions.
  • Precision Adjustability – Corrects alignment, re-centers the rear axle, and restores proper pinion angle, accommodating lifts from 0 to 6 inches.
  • Eliminates Driveline Vibrations – Adjustable upper control arms allow for precise pinion angle correction, reducing stress on the driveshaft and eliminating unwanted vibrations.
  • Tapered Polyurethane Bushings – Reduces vibration, improves articulation, and enhances ride quality over standard rubber bushings.
  • Improved Ride Stability – Addresses rear-end instability, excessive movement, and tire wear, ensuring a smoother ride on and off the road.
  • Recommended Pairing for a Complete Suspension Solution – For full rear-end alignment and handling improvements, pair with our Cruise Series Rear Track Bar (CRS-J-JL-RTB1).

Two-Stage Powder Coating for Maximum Protection

To ensure long-lasting durability, every control arm undergoes a two-stage powder coating process: Zinc Primer Base Coat – Prevents rust and corrosion, ensuring protection in harsh environments. Customizable Top Coat – Choose from 10 available colors to match your vehicle’s aesthetics and add a personal touch.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series Rear Control Arm Set is built with the highest standards of American craftsmanship, ensuring consistent, reliable performance in all driving conditions.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

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!
