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.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

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.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.
