Optimized Performance for Stability and Control
Eliminate axle misalignment, vibration, and rear-end instability with our Cruise Series Rear Upper Control Arms, designed specifically for Jeep Grand Cherokee WK models from 2005-2010. These control arms provide critical pinion angle correction, ensuring driveline stability, improved handling, and long-term durability—whether you're tackling tough trails or cruising on the highway.
Key Features and Benefits
- Heavy-Duty Steel Construction – Built to withstand harsh terrain and heavy loads while ensuring maximum durability.
- Adjustable for Perfect Pinion Angle – Maintains proper alignment and driveline geometry for lifts from 0 to 6 inches.
- Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) while improving ride comfort and flexibility.
- Greaseable and Rebuildable Joints – Designed for easy maintenance and long-term performance, keeping your suspension system in peak condition.
- Recommended Pairing – Combine with Cruise Series Rear Lower Control Arms (CRS-J-WK-RL2) for complete rear-end alignment and axle recentering.
Precision Alignment and Drivability Enhancement
When lifting your Jeep Grand Cherokee WK, the rear pinion angle shifts, leading to driveline vibrations, premature wear, and unpredictable handling. These adjustable upper control arms allow precise pinion angle correction, ensuring smooth power delivery and reduced drivetrain stress. By pairing them with our Rear Lower Control Arms, you get full axle recentering and alignment correction, preventing excessive tire wear and instability.
Two-Stage Powder Coating for Maximum Durability
All control arms go through a two-stage powder coating process to ensure corrosion resistance and long-lasting durability: Zinc primer base coat – Provides enhanced rust protection. Durable top coat – Available in 10 color options, allowing you to customize your suspension’s look.
