Enhance Your Jeep Wrangler JL’s Handling and Stability

Enhance your Jeep Wrangler JL’s handling, stability, and off-road capability with the Camp Series Front Control Arms Set. Designed for 2018-Present models, this set corrects factory caster deficiencies, restores proper suspension geometry, and provides unmatched strength and adjustability. Whether you're tackling off-road terrain or cruising on highways, these control arms will significantly improve your vehicle’s driveability.

Key Features and Benefits

  • Corrects Factory Caster Issues – The stock Jeep JL suspension often suffers from insufficient caster, leading to wandering steering and poor highway stability. These control arms restore caster angle, improving steering control and overall handling.
  • Heavy-Duty DOM Tubing Construction – Built from 1.75" OD DOM Tubing for the lower control arms and 1.5" OD DOM Tubing for the upper control arms, both with a .313" wall thickness, providing superior strength compared to factory components.
  • Optimized Suspension Geometry – Fully adjustable to accommodate lifts from 0 to 6 inches, allowing for precise alignment correction, axle recentering, and optimal suspension setup.
  • Johnny Joint and Polyurethane Bushing Combo – Equipped with Johnny Joints at the adjusting ends for maximum articulation and tapered polyurethane bushings at the axle ends for vibration dampening and improved ride comfort.
  • Recommended Pairing – For the ultimate front-end upgrade, pair this set with our Camp Series Front Track Bar (CMP-J-JL-FTB1) to ensure precise axle centering and optimal suspension performance.

Achieve Perfect Alignment and Driveability

Lifting your Jeep without correcting caster and axle positioning can result in unstable steering, poor tracking, and reduced handling. The Camp Series Front Control Arms Set corrects these issues by:

  • Restoring proper caster angle for improved front-end stability.
  • Ensuring a properly aligned suspension setup to prevent premature tire wear and drivetrain strain.

Two-Stage Powder Coating for Maximum Durability

Each control arm is coated using our two-stage powder coating process, ensuring maximum corrosion resistance and long-lasting protection: Zinc primer base coat provides a strong rust barrier. Top coat available in 10 colors, allowing for customization to match your Jeep’s aesthetic while adding an extra layer of durability.

Proudly Made in the USA

The Camp Series is proudly manufactured in Orem, UT, using locally sourced materials to maintain top-tier quality control. We oversee the entire production process, ensuring each control arm meets our high durability and performance standards.

Optional Hardware Upgrade

This kit is designed for straightforward installation using factory hardware.

If your Jeep has rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, for a hassle-free installation.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

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.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

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!

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.
