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.

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.

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.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

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.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

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!

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)
