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.

What’s Included in the Kit?

  • Front Upper Control Arms (CMP-J-JL-FU2)
  • Front Lower Control Arms (CMP-J-JL-FL2)

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.

In Conclusion

The Camp Series Front Control Arms Set is the ultimate upgrade for Jeep Wrangler JL owners looking to correct caster, improve stability, and optimize suspension performance. Whether you're navigating rocky terrain or driving at highway speeds, these control arms will enhance handling, durability, and ride quality.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

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 :) .

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …

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 wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.
