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.


Each rebuild kit includes all necessary components to replace and restore wearable parts.

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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!
