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.

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!

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4
