Product Details

Correct Your Caster and Take Full Control of Your Suspension

Upgrade your Jeep Gladiator JT (2020-Present) with the Camp Series Front Control Arms Set, designed to correct the factory caster deficiency while improving axle positioning, handling, and overall suspension performance. This set includes Front Upper Control Arms and Front Lower Control Arms, offering a complete solution to regain stability, steering precision, and ride quality.

Key Features and Benefits

  • Corrects Caster for Improved Driveability – The Gladiator’s factory suspension lacks sufficient caster, leading to unstable steering and wandering at higher speeds. These control arms restore proper caster angles, improving handling, cornering, and high-speed stability.
  • Superior Strength and Durability – Constructed from 1.75" OD DOM Tubing for the lowers and 1.5" OD DOM Tubing for the uppers, both with a .313" wall thickness, these arms are built to withstand aggressive off-road conditions while maintaining on-road comfort.
  • Johnny Joint and Polyurethane Bushing Combination – Features Johnny Joints at the adjustable ends for maximum articulation and tapered polyurethane bushings at the axle ends for vibration dampening and long-term durability.
  • Adjustable for Lifted Vehicles – Accommodates suspension lifts from 0 to 6 inches, allowing for precise axle re-centering and alignment correction. For lifts over 6 inches, contact us for additional options.
  • Recommended Pairing – For total front-end stability and precise axle alignment, we recommend pairing these control arms with the Camp Series Front Track Bar (CMP-J-JT-FTB1) for the ultimate Gladiator suspension upgrade.

Optimized Suspension Performance

The factory Gladiator suspension geometry struggles with caster misalignment, which can cause vague steering and reduced handling precision. The Camp Series Front Control Arms correct these issues, keeping your axle properly positioned and suspension dialed in, whether you're on the road or the trail.

Two-Stage Powder Coating for Maximum Durability

Each control arm undergoes a two-stage powder coating process for superior protection against rust and corrosion. A zinc primer base coat ensures long-term resistance, while the top coat (available in 10 colors) lets you customize your Jeep’s look.

Proudly Made in the USA

All Camp Series components are designed and manufactured in Orem, UT. By keeping production in-house, we ensure strict quality control while supporting American manufacturing.

Straightforward Installation

The Camp Series Front Control Arms Set is designed for easy bolt-on installation using factory hardware. If your stock bolts are rusted or worn, we offer optional Grade 8 hardware kits for a hassle-free installation.


  • Vehicle Fitment: Jeep Gladiator JT 20+ – Designed to restore proper caster, improve steering precision, and enhance suspension geometry.

  • CORE Advantage: Adjusts caster angle to improve high-speed stability, reduce steering wander, and enhance overall drivability.

  • Adjustability: Adjustable from 0 to 6 inches of lift, ensuring precise axle centering and pinion angle correction for a properly aligned suspension.

  • Construction: Heavy-duty 1.75" OD 5/16” wall DOM Tubing for the lowers and 1.5" OD 5/16” wall DOM Tubing for the uppers, offering superior strength and off-road durability.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

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.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

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!

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
