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!


  • Vehicle Fitment: Jeep Gladiator JT 20+ – Improves front-end alignment by optimizing axle positioning and steering stability.

  • Adjustability: Designed for lifts from 0 to 6 inches, allowing precise alignment corrections to re-center the axle and fine-tune suspension geometry.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!
