Performance and Comfort

Upgrade your off-road capability and on-road handling with our Cruise Series Front Upper Control Arms. Engineered for Jeep Cherokee XJ (1984-2001) and Jeep Comanche MJ (1986-1992), these control arms are a significant upgrade over factory components, offering superior strength, adjustability, and enhanced ride quality.

Key Features and Benefits

  • Precision Adjustability – Designed to accommodate lifts from 0 to 6 inches, these control arms allow for accurate axle centering, pinion angle correction, and caster adjustments, eliminating wandering and rut tracking on the road.
  • Durable Heavy-Duty Steel Construction – Built from high-strength steel tubing, ensuring maximum durability for off-road adventures and daily driving.
  • Tapered Polyurethane Bushings – Designed to reduce Noise, Vibration, and Harshness (NVH) while improving articulation and longevity. These greaseable and rebuildable bushings provide a smoother, quieter ride compared to factory rubber bushings.
  • Unique U-Bracket Design – The axle-end bracket allows for secure mounting to the factory axle bushing, ensuring proper alignment and stability.
  • Recommended Pairing – For complete front-end control and axle stability, pair these with our Cruise Series Front Lower Control Arms (CRS-J-XJMJ-FL2) to fully recenter your axle and fine-tune your caster and pinion angles.

Eliminate Steering Instability and Improve Ride Quality

Lifting your Jeep affects the caster and pinion angles, which can lead to vague steering, excessive wander, and premature driveline wear. Our adjustable Front Upper Control Arms restore precise suspension geometry, ensuring optimal drivability at any lift height. When combined with Cruise Series Front Lower Control Arms, this setup offers total front-end stability, eliminating wandering and improving highway and trail performance.

Two-Stage Powder Coating for Maximum Durability

Every Cruise Series Control Arm undergoes a two-stage powder coating process for exceptional corrosion resistance. Zinc primer base coat – Prevents rust and enhances durability. Durable top coat – Available in 10 color options for a customized suspension setup.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series components are built in-house to meet strict quality control standards, ensuring superior craftsmanship and competitive pricing.

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 seamless installation.


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

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.

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.

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.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
