Performance and Comfort

Upgrade your Jeep Wrangler TJ or LJ with the Cruise Series Rear Control Arm Set, designed to enhance both off-road capability and on-road comfort. This set includes adjustable upper and lower rear control arms, significantly improving axle alignment, suspension articulation, and overall drivability.

Built to withstand rugged trails and highway conditions alike, this upgrade ensures long-term durability and superior performance over factory components.

Key Features and Benefits

  • Enhanced Strength and Durability – Built from heavy-duty steel tubing, these control arms provide superior strength over factory components.
  • Precision Adjustability – Fully adjustable to accommodate 0 to 6 inches of lift, ensuring proper axle centering and pinion angle correction.
  • Optimized Drivability – Corrects rear axle misalignment and improves handling, reducing tire wear and suspension stress.
  • Recommended Pairing – For complete rear-end alignment and full pinion angle control, pair with our Cruise Series Rear Track Bar (CRS-J-TJLJ-RTB1).

Full Rear Suspension Control

When lifting your Jeep, improper pinion angles and axle misalignment can lead to driveline vibrations and handling instability. This rear control arm set allows for precise axle centering and pinion angle adjustments, eliminating these common suspension issues.

When paired with our Rear Track Bar, this combination ensures optimal handling and maximum rear-end stability in all driving conditions.

Two-Stage Powder Coating

Each control arm is coated with a two-stage powder coating process for maximum durability: Zinc primer base coat provides superior corrosion resistance. Top coat available in 10 color options, allowing you to personalize the look of your suspension components.

Made in the USA

All Cruise Series components are proudly manufactured in Orem, UT, ensuring the highest quality craftsmanship while supporting American manufacturing.

Optional Hardware Upgrade

  • Our Rear Control Arm Set is designed for easy installation using factory hardware.
  • For those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately, to make the installation process seamless.

Whether you’re tackling tough trails or cruising on the highway, these control arms will correct pinion angle, recenter the rear axle, and provide enhanced drivability.

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.

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.

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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.
