Precision Alignment Caster Control

If you've lifted your Jeep Gladiator JT, maintaining proper caster and axle alignment is critical for stability, handling, and overall drivability. The Cruise Series Front Upper Control Arms correct alignment issues caused by lifting, ensuring that your Jeep tracks straight without wandering or following ruts in the road.

For a complete solution, we recommend pairing these with our Cruise Series Front Lower Control Arms (CRS-J-JT-FL2) to fully recenter your axle, dial in caster correction, and maximize stability—essential for improved steering feel and highway driving.

Key Features and Benefits

  • Restores Proper Caster Angle – Essential for maintaining stability, steering precision, and preventing wandering.
  • Axle Re-centering for Lifted Vehicles – Ensures optimal alignment correction when lifting from 0 to 6 inches.
  • Durable Polyurethane Bushings – Provides smooth articulation and reduced road vibrations compared to stock rubber bushings.
  • Heavy-Duty DOM Steel Construction – Built for maximum strength and off-road durability.
  • Recommended Pairing for Full Alignment Control – Combine with Cruise Series Front Lower Control Arms (CRS-J-JT-FL2) for complete axle re-centering and stability enhancement.

Two-Stage Powder Coating for Maximum Protection

Each control arm undergoes a two-stage powder coating process for long-lasting durability: Zinc Primer Base Coat – Provides superior corrosion resistance in extreme conditions. Customizable Top Coat – Available in 10 colors to match your build while adding an extra layer of protection.

Made in the USA

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

Optional Hardware Upgrade

Our Front Upper Control Arms install using factory hardware. However, if your vehicle has rusted, seized, or worn-out bolts, we offer optional Grade 8 hardware kits for a secure and hassle-free installation.

For full front-end control, pair these with our Cruise Series Front Lower Control Arms (CRS-J-JT-FL2) to maximize caster correction, axle centering, and steering stability. Upgrade today and experience improved handling, stability, and ride quality—on and off the trail!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store
