The Ultimate Hard-Component Suspension Solution
Upgrade your Jeep Wrangler JL’s suspension with the Cruise Series 10-Piece Kit, a complete solution for correcting caster issues, eliminating wandering, following ruts in the road, and reducing death wobble. This all-in-one suspension overhaul replaces your entire set of control arms and track bars, giving you full control over alignment, axle centering, and suspension geometry—all while providing enhanced durability and off-road capability. From daily driving to extreme off-roading, this kit outperforms factory components, ensuring improved handling, stability, and ride comfort on any terrain.
Key Features Benefits
- Eliminates caster issues steering instability – Regain full caster control, reducing wandering, rut-following, and loose steering after lifting your Jeep.
- Corrects axle positioning pinion angle – Adjustable control arms allow precise re-centering of axles to prevent driveline vibrations and premature component wear.
- Reduces death wobble – The adjustable front track bar helps eliminate steering oscillations by maintaining a centered axle and proper suspension geometry.
- Heavy-duty steel construction – Built from high-strength steel tubing, these components deliver long-term durability and maximum off-road capability.
Fix Common Jeep JL Suspension Issues
The Jeep Wrangler JL suffers from insufficient caster angle from the factory, and when lifted, this issue is exacerbated—leading to wandering, poor handling, and excessive steering corrections. This kit completely solves those problems by correcting caster angles, re-centering the axle, and optimizing alignment.
Additionally, this kit is a major solution for death wobble—a violent front-end oscillation often caused by poor track bar alignment, worn bushings, and incorrect suspension geometry. When paired with upgraded steering components, this kit greatly reduces or even eliminates death wobble by keeping the axle properly centered and the suspension geometry correct.
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 re-use factory hardware, with optional Grade 8 hardware kits available 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.
Each rebuild kit includes all necessary components to replace and restore wearable parts.
