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!

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

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

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.
