Optimized Steering and Stability

Upgrade your Jeep Wrangler TJ/LJ’s handling and stability with the Cruise Series Front Control Arm Set, engineered for 1997-2006 models. This kit includes both Front Upper Control Arms (CRS-J-TJLJ-FU2) and Front Lower Control Arms (CRS-J-TJLJ-FL2), delivering superior strength, caster correction, and alignment precision. Whether tackling off-road terrain or driving at highway speeds, this set eliminates wandering, rut tracking, and steering instability, giving you a smoother, more controlled ride.

Key Features and Benefits

  • Corrects Caster Angle Deficiencies – Restores proper caster geometry, preventing wandering, rut tracking, and unpredictable steering at high speeds.
  • Full Front Axle Alignment Re-Centering – Works together to keep your axle properly positioned for better handling and suspension longevity.
  • Adjustable for 0 to 6 Inches of Lift – Allows precise suspension tuning for lifted Jeeps. Contact us for custom solutions beyond 6 inches.
  • Durable Steel Construction – Heavy-duty steel tubing provides maximum strength and impact resistance.
  • Recommended Pairing – For complete stability, pair with our Cruise Series Front Track Bar (CRS-J-TJLJ-FTB1) to keep your axle centered and eliminate bump steer.

Restore Control and Driving Confidence

Factory control arms often fail to maintain proper caster when lifting a Jeep, leading to unstable steering and premature tire wear. Our adjustable Front Control Arms restore optimal caster angles, ensuring:

  • Enhanced directional stability
  • Tighter handling
  • Smoother highway cruising

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for superior corrosion resistance: Zinc primer base coat provides rust protection. Top coat available in 10 colors, allowing you to customize your suspension components.

Made in the USA

Every Cruise Series component is proudly manufactured in Orem, UT. We maintain complete control over design, production, and quality assurance, ensuring long-lasting durability and reliability.

Optional Hardware Upgrade

  • These control arms can be installed using factory hardware.
  • For rusted or stubborn bolts, we offer Grade 8 hardware kits separately to make installation seamless and hassle-free.

For the best results, pair with our Front Track Bar (CRS-J-TJLJ-FTB1) for complete front-end alignment and stability.

Upgrade today and experience true suspension control!


Each rebuild kit includes all necessary components to replace and restore wearable parts.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!
