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!

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

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!

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.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.
