Regain Proper Caster Improve Front-End Stability

When lifting your Jeep Wrangler JL, maintaining proper caster angle is crucial for steering stability, handling, and overall drivability. Factory suspension geometry is already lacking in caster, and adding a lift can worsen the issue—leading to wandering, following ruts in the road, and a loose steering feel.

Our Cruise Series Front Upper Control Arms are designed to fine-tune caster correction, improving steering precision, high-speed stability, and tire wear. When paired with our Cruise Series Front Lower Control Arms (CRS-J-JL-FL2), this combination completely restores axle centering, suspension alignment, and caster angles, offering a full front-end suspension solution for lifted Jeeps.

What’s Included in the Kit?

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

Key Features Benefits

  • Restores proper caster angle – Adjustability allows fine-tuning of suspension geometry, eliminating wandering, pulling, and unstable steering after lifting your Jeep.
  • Improves steering response high-speed stability – Proper caster helps keep your steering wheel centered and reduces fatigue from constant corrections.
  • Heavy-duty steel construction – Built from high-strength steel tubing, these arms deliver long-lasting durability and enhanced off-road performance.
  • Unique U-bracket design – The axle end U-bracket mounts directly to the factory axle bushing, maintaining a secure and quiet ride.
  • Recommended pairing for maximum stability – Combine with our Cruise Series Front Lower Control Arms (CRS-J-JL-FL2) to fully correct caster, re-center the axle, and eliminate steering instability.

Adjustability for Lifts from 0 to 6 Inches

Whether you're at factory height or running a 6-inch lift, these fully adjustable control arms allow precise caster correction and suspension alignment. If you’re running a lift over 3 inches, pairing with our adjustable Front Lower Control Arms ensures full caster correction and axle re-centering for maximum control. For lifts beyond 6 inches, contact us for additional options.

Durable Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process: Zinc primer base coat – Ensures maximum rust and corrosion protection, especially in harsh climates. Durable top coat – Available in 10 color options, allowing you to customize your Jeep’s suspension components while adding extra durability.

Proudly Made in the USA

Manufactured in Orem, UT, these control arms are built with 100% American-made materials to exacting quality standards. By choosing our Cruise Series, you support local manufacturing and high-quality craftsmanship.

Optional Hardware Upgrade

Our Cruise Series Front Upper Control Arms are designed to reuse your Jeep’s factory mounting hardware. If your existing bolts are rusted, worn, or difficult to remove, we offer optional Grade 8 hardware kits separately for a hassle-free installation and added durability.

In Conclusion

If you’re experiencing wandering, pulling, or unstable steering after lifting your Jeep, proper caster correction is the key to restoring drivability. The Cruise Series Front Upper Control Arms provide adjustability for caster correction, improving steering response, axle positioning, and high-speed stability.

For the best results, pair with our Cruise Series Front Lower Control Arms (CRS-J-JL-FL2) to create a complete front-end suspension upgrade, eliminating wandering, rut-following, and excessive steering corrections.

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 met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

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.

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.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!
