The Ultimate Suspension and Steering Upgrade

The Camp Series 12-Piece Kit is the ultimate suspension and steering upgrade for the Jeep Gladiator JT (2020-Present). This comprehensive kit replaces every major suspension and steering component, giving you full control over axle alignment, caster correction, pinion angle, and steering precision. Whether you're tackling rugged trails or maintaining highway stability, this kit eliminates death wobble, improves steering response, and enhances overall drivability, ensuring a smooth, predictable, and controlled ride in all conditions.

Key Features and Benefits

  • Complete suspension steering overhaul – Provides total control over axle positioning, caster correction, pinion angle, and steering geometry for superior performance on and off-road.
  • Eliminates death wobble improves handling – Adjustable track bars, control arms, and the 2.5-ton aluminum steering kit keep axles centered, minimize steering instability, and ensure a smoother, more predictable driving experience.
  • Heavy-duty steering system – The 2.5-ton aluminum steering kit increases strength and control, significantly improving steering precision and stability on tough trails and high-speed roads.
  • Optimized for lifted vehicles – Fully adjustable to accommodate suspension lifts from 0 to 6 inches, allowing precise alignment correction and axle centering at any ride height.

Solve Factory Caster Issues

Proper caster correction improves steering feel, high-speed stability, and overall handling, ensuring your Jeep tracks straight and drives smoothly.

Recommended Pairing

To further refine handling and stability, pair this kit with the Camp Series Sway Bar End Link Set (CMP-J-JT-ELS4) for a complete performance upgrade.

Durable Two-Stage Powder Coating

Each component undergoes a zinc primer base coat for corrosion resistance, followed by a top coat available in 10 colors for a personalized look.

Simple Installation

Designed for easy bolt-on installation using factory hardware, with optional Grade 8 hardware kits available separately for rusted or stubborn bolts.

Notes: Some, (not all) factory axle mounts need to be "clearanced" to accept our larger bar. If needed, it is only a minor amount of trimming to be done. This applies to the front track bar only. Please see our Youtube channel for a video addressing this.

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.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.
