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.

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.

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!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

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!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
