Enhanced Comfort, Pinion Angle Adjustment, and Flexibility

Upgrade your Jeep Gladiator JT’s (2020-Present) suspension with the Camp Series Rear Upper Control Arms, designed to improve on-road comfort, off-road flexibility, and rear pinion angle adjustment. These control arms provide superior strength and adjustability, ensuring precise alignment correction and enhanced suspension performance over factory components.

Key Features and Benefits

  • Heavy-Duty Construction – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, providing exceptional strength and durability for off-road demands.
  • Adjustable for Lifted Vehicles – Designed to accommodate lifts from 0 to 6 inches, allowing for precise axle re-centering and pinion angle correction.
  • Johnny Joint Tapered Polyurethane Bushing – A Johnny Joint at the adjustable end enhances articulation, while the polyurethane bushing at the axle end absorbs vibration for a smoother ride.
  • Improved Rear Suspension Geometry – Pair with the Camp Series Rear Lower Control Arms (CMP-J-JT-RL2) for full adjustability and optimal axle positioning, ensuring precise pinion angle adjustment and rear suspension control.

Two-Stage Powder Coating for Maximum Protection

Each control arm undergoes a two-stage powder coating process to ensure long-lasting durability and corrosion resistance. Zinc primer base coat protects against rust. Durable top coat, available in 10 custom colors, provides a tough, stylish finish.

Proudly Made in the USA

Manufactured in Orem, UT, our Camp Series components are built to the highest standards of American craftsmanship. We oversee the entire production process to ensure top-tier quality and durability.

Simple Installation

Designed for easy bolt-on installation using factory hardware.

  • If your existing bolts are rusted or difficult to remove, we offer optional Grade 8 hardware kits separately for a hassle-free installation.

For the ultimate rear suspension upgrade, pair them with the Camp Series Rear Lower Control Arms (CMP-J-JT-RL2) to achieve full control over your axle positioning and handling performance.

Upgrade today for unmatched strength, flexibility, and American-made quality!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

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.

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.

Excellent, strong, and durable products—perfect for both on-road and off-road applications. The customer service is outstanding—friendly, knowledgeable, and extremely helpful with understanding installation and ensuring I got exactly what I needed. I would definitely order again. Top-notch company with high-quality products made right here in the U.S.A.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

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.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)
