The Ultimate Suspension and Steering Solution

Transform your Jeep Gladiator JT (2020-Present) with the Cruise Series 12-Piece Kit, a comprehensive upgrade designed to eliminate caster deficiencies, axle misalignment, driveline vibrations, wandering, rut-following, and even death wobble. This kit replaces all key hard components, ensuring precise alignment, axle centering, and unmatched handling both on-road and off-road.

For even greater suspension stability, we recommend pairing this kit with the Cruise Series Front Rear End Link Set (CRS-J-JT-ELS4) to complete your Gladiator’s handling transformation.

Each component is built with high-strength DOM steel tubing and RockJock Johnny Joints or polyurethane bushings, offering exceptional durability, articulation, and longevity for any driving condition.

Key Features and Benefits

  • Eliminates death wobble steering play – Corrects axle positioning and steering geometry for enhanced stability and precise steering response.
  • Fixes caster deficiencies wandering – Regains proper caster angle, improving drivability and eliminating wandering or rut-following.
  • Centers axles corrects driveline angles – Ensures proper front and rear axle alignment, reducing driveline vibrations and premature wear.
  • Built for 0 to 6 inches of lift – Fully adjustable control arms and track bars allow for precise suspension tuning at any ride height.
  • Heavy-duty steering upgrade – The 2.5-ton aluminum steering kit provides maximum control and durability in the most extreme conditions.

Recommended Pairing for Ultimate Handling

Combine with the Cruise Series Front Rear End Link Set (CRS-J-JT-ELS4) to further enhance stability and sway control.

Durable Two-Stage Powder Coating

Each component undergoes a zinc primer base coat for corrosion resistance, followed by a top coat available in 10 colors for a personalized look.

Optional Hardware Upgrade

Designed to reuse factory hardware, with optional Grade 8 hardware kits available separately for rusted or worn-out bolts.

Notes: Some, (not all) factory axle mounts need to be "clearanced" to accept our larger bar. If needed, it is only a minor amount of trimming to be done. This applies to the front track bar only. Please see our Youtube channel for a video addressing this.


  • Vehicle Fitment: Jeep Gladiator JT 20+ – Eliminates steering instability, axle misalignment, and driveline vibrations for a smoother, more controlled ride.

  • CORE Advantage: A full hard-component upgrade, correcting caster deficiencies, wandering, and death wobble while optimizing axle centering and handling.

  • Adjustability: Designed for 0 to 6 inches of lift, allowing fine-tuned suspension geometry, steering response, and drivability for any build.

  • Construction: Heavy-duty DOM steel control arms, adjustable track bars, and a 2.5-ton aluminum steering kit ensure maximum durability, strength, and precision.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

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.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!
