Performance and Comfort

Upgrade your Jeep Wrangler TJ or LJ with the Cruise Series Rear Control Arm Set, designed to enhance both off-road capability and on-road comfort. This set includes adjustable upper and lower rear control arms, significantly improving axle alignment, suspension articulation, and overall drivability.

Built to withstand rugged trails and highway conditions alike, this upgrade ensures long-term durability and superior performance over factory components.

Key Features and Benefits

  • Enhanced Strength and Durability – Built from heavy-duty steel tubing, these control arms provide superior strength over factory components.
  • Precision Adjustability – Fully adjustable to accommodate 0 to 6 inches of lift, ensuring proper axle centering and pinion angle correction.
  • Optimized Drivability – Corrects rear axle misalignment and improves handling, reducing tire wear and suspension stress.
  • Recommended Pairing – For complete rear-end alignment and full pinion angle control, pair with our Cruise Series Rear Track Bar (CRS-J-TJLJ-RTB1).

Full Rear Suspension Control

When lifting your Jeep, improper pinion angles and axle misalignment can lead to driveline vibrations and handling instability. This rear control arm set allows for precise axle centering and pinion angle adjustments, eliminating these common suspension issues.

When paired with our Rear Track Bar, this combination ensures optimal handling and maximum rear-end stability in all driving conditions.

Two-Stage Powder Coating

Each control arm is coated with a two-stage powder coating process for maximum durability: Zinc primer base coat provides superior corrosion resistance. Top coat available in 10 color options, allowing you to personalize the look of your suspension components.

Made in the USA

All Cruise Series components are proudly manufactured in Orem, UT, ensuring the highest quality craftsmanship while supporting American manufacturing.

Optional Hardware Upgrade

  • Our Rear Control Arm Set is designed for easy installation using factory hardware.
  • For those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately, to make the installation process seamless.

Whether you’re tackling tough trails or cruising on the highway, these control arms will correct pinion angle, recenter the rear axle, and provide enhanced drivability.

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!

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!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

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!!!

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽
