Eliminate Caster Issues Regain Full Front-End Control

Take control of your Jeep Wrangler JL's suspension with the Cruise Series Front Control Arm Set, engineered to correct alignment, re-center the front axle, and restore proper caster angle. From the factory, caster angles are often insufficient, leading to wandering, instability, and tracking ruts in the road. When lifting your JL, these deficiencies become even more pronounced.

This complete Front Upper and Lower Control Arm Set fully corrects those issues, delivering improved handling, steering precision, and superior off-road flexibility.

What’s Included in the Kit?

  • Pair of Cruise Series Front Upper Control Arms (CRS-J-JL-FU2)
  • Pair of Cruise Series Front Lower Control Arms (CRS-J-JL-FL2)

Key Features Benefits

  • Corrects Caster Angle for Stability – Restores proper caster geometry on lifts from 0 to 6 inches, eliminating wandering and rut tracking.
  • Re-Centers the Axle – Ensures the front axle remains properly aligned in the wheel well for optimal suspension performance.
  • Heavy-Duty Steel Construction – Built from strong steel tubing for superior strength and durability over factory parts.
  • Tapered Polyurethane Bushings – Provides enhanced responsiveness, reduced road noise, and improved ride quality.
  • Recommended Pairing – For a complete front-end suspension solution and reduced risk of death wobble, pair with the Cruise Series Front Track Bar (CRS-J-JL-FTB1).

Precision Engineering for Maximum Control

The Front Lower Control Arms are responsible for correcting caster and centering the axle, while the Front Upper Control Arms provide fine-tuned alignment adjustments.

When combined, this kit fully restores stability and driveability, making your JL handle better both on-road and off-road.

Two-Stage Powder Coating for Maximum Durability

Each control arm is finished with a premium two-stage powder coating process: Zinc Primer Base Coat – Ensures superior corrosion resistance and long-term durability. Durable Top Coat – Available in 10 custom colors to match your Jeep’s build.

Proudly Made in the USA

Designed and manufactured in Orem, UT, this kit is a testament to high-quality American craftsmanship. By sourcing raw materials locally and overseeing the entire production process, we guarantee exceptional durability and performance.

Optional Hardware Upgrade

  • Our Cruise Series Front Control Arm Set installs 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

If you're lifting your Jeep Wrangler JL, the Cruise Series Front Control Arm Set is a must-have upgrade to restore caster, re-center your axle, and eliminate wandering.

Pair with our Front Track Bar for even greater stability and reduced death wobble risk.

Upgrade today and experience a more controlled, comfortable, and capable Jeep!

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.

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.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.
