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!

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.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you 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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!
