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.

Upgrade today and experience the CORE 4X4 difference!

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

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

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.
