Unparalleled Suspension Performance for Jeep Cherokee XJ (1984-2001)

Upgrade your Jeep Cherokee XJ with the Camp Series Long Arm Upgrade Kit, the ultimate suspension overhaul designed to deliver unmatched strength, stability, and ride quality. Unlike radius-style long arm systems that compromise performance and reliability, our true long lower and upper control arms redefine your vehicle’s capabilities, ensuring superior articulation, geometry correction, and suspension travel for both on- and off-road adventures.

Key Features and Benefits

  • Superior Suspension Travel – With true long arms, the suspension cycles on a longer arc, allowing the axle to move more naturally for a smoother, more controlled ride.
  • Heavy-Duty Construction – Built from .313-inch wall DOM tubing, featuring Johnny Joints and tapered polyurethane bushings for superior durability and vibration dampening.
  • Enhanced Stability – Corrects suspension geometry, keeping wheels planted and improving handling on highways, trails, and steep climbs.
  • Fully Adjustable Design – Accommodates lifts from as low as 2 inches up to high-clearance setups, allowing precise axle alignment and pinion angle correction.
  • High-Clearance Crossmember – A 3-piece design ensures easy drivetrain access without sacrificing strength.

Recommended Pairing

For optimal performance, pair this kit with our Camp Series Track Bar (CMP-J-XJ-FTB1) to further enhance axle centering and front-end stability.

Maximize Performance and Ride Quality

The Camp Series Long Arm Upgrade Kit is engineered to optimize your Jeep’s suspension geometry, reducing binding and allowing for maximum articulation. Unlike short arm setups that limit flexibility and stress components, this system provides a smoother ride, improved axle travel, and better overall performance—whether rock crawling, towing, or daily driving.

Two-Stage Powder Coating

Every component undergoes a two-stage powder coating process for superior corrosion resistance and long-term durability.

Zinc Primer Base Coat – Protects against rust and corrosion.

Durable Top Coat – Available in 10 custom colors to match or contrast your Jeep’s suspension while adding extra durability.

Made in the USA

We proudly manufacture all Camp Series products in our Orem, UT facility, ensuring the highest standards of quality and craftsmanship. By sourcing local materials and overseeing the entire production process, we guarantee American-made excellence in every part.

Optional Hardware Upgrade

The Camp Series Long Arm Upgrade Kit is designed for bolt-on installation, with optional weld surfaces for added strength. For those needing replacement hardware, we offer optional Grade 8 kits separately for a hassle-free installation.

 

  • Vehicle Fitment: Jeep Cherokee XJ 84-01 – Designed to maximize suspension travel, improve handling, and enhance stability on and off the road.

  • CORE Advantage: True long lower and upper control arms create a wider suspension arc, improving articulation, reducing axle bind, and delivering a smoother, more controlled ride. Unlike radius-style systems, this design corrects geometry without compromising performance.

  • Adjustability: Engineered for lifts ranging from 2 inches to high-clearance setups, allowing precise pinion angle correction, axle centering, and optimized alignment for any build.

  • Construction: Heavy-duty 5/16” wall DOM tubing for superior strength, featuring a high-clearance 3-piece crossmember for easy drivetrain access and 1/4-inch plate steel brackets for unmatched durability.

  • 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.

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

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.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!
