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.
