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.

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.

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.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

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.

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.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

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!

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.
