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.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.
