  • Rear Lower Control Arms (CRS-J-WK-RL2)
  • Rear Track Bar (CRS-J-WK-RTB)

Key Features and Benefits

  • Enhanced Strength Durability – Heavy-duty steel tubing ensures superior longevity compared to factory parts.
  • Optimized Adjustability – Designed to accommodate 0 to 6 inches of lift, allowing precise pinion angle correction and rear axle re-centering.
  • Tapered Polyurethane Bushings – Provides better responsiveness, smoother articulation, and reduced vibrations.
  • Recommended Pairing – To complete your suspension upgrade, pair this kit with high-performance shocks and springs to build a fully optimized lift kit.

Total Rear-End Stability Adjustability

Lifting your Jeep can disrupt suspension geometry, leading to rear-end wandering, improper pinion angles, and premature drivetrain wear. Our adjustable control arms and rear track bar work together to re-center your axle, correct driveline angles, and restore handling precision. With the ability to fine-tune your suspension setup, this kit ensures optimal performance whether you're navigating rugged trails or cruising on the highway.

Two-Stage Powder Coating for Maximum Durability

To extend product life and enhance corrosion resistance, all components undergo a two-stage powder coating process. A zinc primer base coat provides rust protection, followed by a durable topcoat available in 10 colors, allowing you to customize your suspension setup.

Made in the USA

Proudly manufactured in Orem, UT, using locally sourced materials. We maintain strict quality control to ensure our products outperform and outlast stock components.

Optional Hardware Upgrade

This kit is designed for a seamless installation using factory hardware. However, for those dealing with rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to make installation effortless.

In Conclusion

The Cruise Series Complete Rear Kit is the ultimate solution for eliminating rear-end wandering, correcting pinion angles, and maximizing stability. Pair it with shocks and springs for a ready-made lift kit that outperforms anything else on the market.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

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.
