Experience Superior Stability, Performance, and Comfort

Upgrade your Jeep's front-end suspension with our Cruise Series Complete Front Kit, engineered for Jeep Cherokee XJ (1984-2001) and Jeep Comanche MJ (1986-1992). This kit delivers exceptional strength, adjustability, and ride quality, significantly improving both off-road performance and on-road comfort while reducing noise, vibration, and harshness (NVH).

Key Features and Benefits

  • Full front-end suspension upgrade – Enhances steering precision, axle centering, and overall stability.
  • Adjustability for proper alignment – Designed to accommodate lifts from 0 to 6 inches, allowing for precise caster correction and axle re-centering.
  • Heavy-duty steel construction – Built to withstand extreme off-road conditions while maintaining durability for daily driving.
  • Tapered polyurethane bushings – Reduces NVH (noise, vibration, and harshness) while offering superior responsiveness and flexibility over standard rubber bushings.

Recommended Pairing

For complete front-end stability and steering precision, pair this kit with the RockJock Currectlync Steering Kit (CE-9701).

Enhanced Stability and Precision Handling

The Cruise Series Complete Front Kit plays a vital role in correcting caster angle and axle positioning after lifting your vehicle. Proper caster correction reduces wandering, rut-following, and eliminates front-end instability, improving high-speed handling and eliminating issues like death wobble when paired with a high-quality steering system.

Two-Stage Powder Coating for Maximum Durability

All components in this kit undergo a two-stage powder coating process for enhanced corrosion resistance and durability. A zinc primer base coat provides superior rust protection, followed by a durable top coat, available in 10 color options to match your vehicle’s aesthetic.

Made in the USA

Proudly manufactured in Orem, UT, every Cruise Series component is precision-engineered and built in-house to meet strict quality standards while supporting American manufacturing.

Optional Hardware Upgrade

This kit is designed for easy installation using factory hardware. However, if your factory bolts are rusted or worn, we offer optional Grade 8 hardware kits separately to ensure a hassle-free installation process.




  • Vehicle Fitment: Jeep Cherokee XJ 84-01, Jeep Comanche MJ 86-92 – Enhances front-end suspension performance by improving axle centering, alignment, and stability for better on-road handling and off-road capability.

  • CORE Advantage: Corrects caster angles and re-centers the axle, reducing wandering, improving steering precision, and eliminating instability, ensuring a smoother ride and better drivability at all speeds.

  • Adjustability: Fully adjustable to accommodate lift heights from 0 to 6 inches, allowing precise caster correction, axle re-centering, and optimal suspension geometry for superior control.

  • Construction: Built from heavy-duty steel with tapered polyurethane bushings to reduce NVH (Noise, Vibration, Harshness), enhancing durability, responsiveness, and comfort over factory 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.

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 don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

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!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

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!
