Regain Control Stability

Eliminate wandering, improve drivability, and regain proper caster angle with the Cruise Series Front Lower Control Arms. Designed specifically for the Jeep Wrangler JL (2018-Present), these control arms address the factory caster deficiency that can lead to wandering, instability, and following ruts in the road—especially after lifting your vehicle. Built for durability and performance, this upgrade provides enhanced on-road handling and superior off-road flexibility.

What’s Included in the Kit?

  • Pair of Cruise Series Front Lower Control Arms (CRS-J-JL-FL2)

Key Features Benefits

  • Corrects caster for improved stability – Restores proper caster angle, eliminating wandering and rut tracking.
  • Heavy-duty steel construction – Provides unmatched strength and durability over factory control arms.
  • Tapered polyurethane bushings – Reduces road noise and enhances responsiveness for a smoother ride.
  • Fully adjustable for lifted vehicles – Accommodates lifts up to 6 inches, ensuring precise alignment correction and axle re-centering.
  • Recommended pairing – For lifts above 3 inches, pair with Cruise Series Front Upper Control Arms (CRS-J-JL-FU2) for full caster control and complete front-end suspension tuning.

Built for Strength Performance

Unlike factory control arms that struggle to maintain alignment after a lift, the Cruise Series Front Lower Control Arms are designed to restore proper suspension geometry. By correcting caster angle, they dramatically improve steering feel, reduce driveline vibrations, and prevent instability.

Two-Stage Powder Coating for Maximum Durability

Every control arm undergoes a rigorous two-stage powder coating process: Zinc primer base coat – Creates a corrosion-resistant foundation for long-term durability. Durable top coat – Available in 10 custom colors for added protection and personalization.

Proudly Made in the USA

Designed and manufactured in Orem, UT, these control arms reflect the highest quality of American craftsmanship. By sourcing materials locally and overseeing the entire production process, we ensure superior durability and performance.

Optional Hardware Upgrade

The Cruise Series Front Lower Control Arms install easily using factory hardware. For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a hassle-free installation.

In Conclusion

Upgrade your Jeep Wrangler JL with the Cruise Series Front Lower Control Arms and experience a drastic improvement in drivability, stability, and ride comfort. By correcting caster angle and eliminating wandering, this upgrade optimizes both daily driving and off-road performance. Pair with our Front Upper Control Arms for full front-end suspension control and take your Jeep’s performance to the next level!

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.

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.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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!

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.
