Total Control Over Caster and Axle Alignment

The Jeep Gladiator JT’s factory suspension suffers from insufficient caster, leading to wandering, instability, and rut tracking—especially after a lift. CORE 4X4’s Cruise Series Front Control Arm Set completely eliminates these issues, allowing for precise caster correction and axle centering. With both front upper and lower control arms, this set gives you full control over your alignment, improving steering response, high-speed stability, and off-road capability.

Key Features and Benefits

  • Corrects Caster Deficiencies – Eliminates wandering, instability, and rut-following by restoring proper caster angles.
  • Re-Centers the Front Axle – Ensures correct wheel placement in the wheel well, improving alignment and tire wear.
  • Adjustable for Lifts (0-6”) – Optimizes suspension geometry for stock height up to 6-inch lift setups.
  • Tapered Polyurethane Bushings – Reduces noise, vibrations, and harshness (NVH) for smoother suspension movement.
  • Heavy-Duty Steel Construction – Built from high-strength steel tubing for superior durability.
  • Recommended Pairing for Maximum Stability – Combine with our Cruise Series Front Track Bar (CRS-J-JT-FTB1) to further reduce death wobble and improve steering precision.

Two-Stage Powder Coating for Maximum Protection

Every control arm undergoes a two-stage powder coating process to ensure long-term durability and corrosion resistance: Zinc Primer Base Coat – Forms a rust-resistant barrier for extreme conditions. Customizable Top Coat – Available in 10 colors to match your Gladiator’s build while adding extra protection.

Made in the USA

Proudly designed, tested, and manufactured in Orem, UT, our Cruise Series Control Arms meet the highest American craftsmanship and quality control standards.

Optional Hardware Upgrade

  • Our Front Control Arm Set installs using factory hardware.
  • However, if your vehicle has rusted, seized, or worn-out bolts, we offer optional Grade 8 hardware kits for a smoother and more secure installation.

For even more front-end control, pair these with our Cruise Series Front Track Bar (CRS-J-JT-FTB1) to further reduce death wobble and optimize steering response.

Upgrade today and take full control of your Jeep’s suspension performance!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

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.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !
