Product Details

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!


  • Vehicle Fitment: Jeep Wrangler TJ/LJ 97-06 – Enhances steering precision, eliminates wandering, and improves overall handling by correcting caster angle deficiencies. Ensures stability both on-road and off-road for lifted Jeeps.

  • CORE Advantage: Provides full front-end suspension control, correcting caster angle and re-centering the front axle. Reduces rut tracking and steering instability while improving responsiveness and suspension articulation.

  • Adjustability: Fully adjustable for 0 to 6 inches of lift, allowing precise caster correction and axle positioning. For lifts above 6 inches, additional modifications may be required for optimal alignment.

  • Construction: Heavy-duty steel tubing for maximum durability and impact resistance. Equipped with high-performance polyurethane bushings to absorb road impacts, reduce noise, and improve articulation over factory rubber components.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

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.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

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.
