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.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!
