Product Details

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.


  • Vehicle Fitment: Jeep Cherokee XJ 84-01, Jeep Comanche MJ 86-92 – Enhances front-end stability, alignment, and handling, improving both on-road performance and off-road capability by restoring caster and pinion angles.

  • CORE Advantage: Corrects suspension geometry to prevent wandering, rut tracking, and driveline wear, ensuring a smoother, more responsive ride and precise steering across all terrains.

  • Adjustability: Fully adjustable for lifts from 0 to 6 inches, allowing for accurate axle centering, caster adjustments, and optimal suspension geometry to maintain drivability and control.

  • Construction: Built from high-strength steel with tapered polyurethane bushings to reduce NVH (Noise, Vibration, Harshness), enhance articulation, and improve ride 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.

  • 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 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.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

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.
