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.

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.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.
