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!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

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.

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.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.
