Optimize Performance and Enhance Comfort
Upgrade both your on-road drivability and off-road capability with the Cruise Series Complete Rear Kit, designed specifically for Jeep Grand Cherokee WK model years 2005-2010. This all-in-one kit enhances axle alignment, corrects pinion angles, and eliminates rear-end instability, delivering a significant improvement over stock suspension components.
Key Features and Benefits
- Enhanced Strength Durability – Heavy-duty steel tubing ensures superior longevity compared to factory parts.
- Optimized Adjustability – Designed to accommodate 0 to 6 inches of lift, allowing precise pinion angle correction and rear axle re-centering.
- Tapered Polyurethane Bushings – Provides better responsiveness, smoother articulation, and reduced vibrations.
- Recommended Pairing – To complete your suspension upgrade, pair this kit with high-performance shocks and springs to build a fully optimized lift kit.
Total Rear-End Stability Adjustability
Lifting your Jeep can disrupt suspension geometry, leading to rear-end wandering, improper pinion angles, and premature drivetrain wear. Our adjustable control arms and rear track bar work together to re-center your axle, correct driveline angles, and restore handling precision. With the ability to fine-tune your suspension setup, this kit ensures optimal performance whether you're navigating rugged trails or cruising on the highway.
Two-Stage Powder Coating for Maximum Durability
To extend product life and enhance corrosion resistance, all components undergo a two-stage powder coating process. A zinc primer base coat provides rust protection, followed by a durable topcoat available in 10 colors, allowing you to customize your suspension setup.

Optional Hardware Upgrade
