Optimized Control and Alignment for Lifted Vehicles
Upgrade your Jeep Grand Cherokee WJ (1999-2004) with the Cruise Series Front Upper Control Arms, engineered to correct alignment issues, optimize suspension geometry, and improve overall ride quality. Whether you're tackling off-road trails or daily driving, these arms deliver enhanced strength and precise adjustability, making them a superior replacement for factory components.
For the best results, we recommend pairing these with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2). Together, these components fully re-center your axle, restore proper caster, and improve handling, reducing wandering, uneven tire wear, and steering instability.
Key Features and Benefits
- Precise Adjustability – Designed to accommodate lifts from 0 to 6 inches, ensuring proper alignment after suspension modifications.
- Enhanced Strength – Built from heavy-duty steel tubing for superior durability compared to factory parts.
- Optimized Suspension Geometry – Corrects caster and pinion angle, reducing driveline vibrations and enhancing steering control.
- High-Performance Polyurethane Bushings – Provides better responsiveness, reduced road noise, and improved suspension flex compared to rubber bushings.
- Recommended Pairing – For full front-end suspension optimization, pair with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2) to fully re-center the axle and maximize handling stability.
Full Caster Correction and Drivability Enhancement
Lifting your Grand Cherokee WJ changes the caster angle, which can cause steering instability, wandering, and uneven tire wear. These adjustable upper control arms allow you to fine-tune caster for improved high-speed stability and responsive steering. When paired with our Front Lower Control Arms (CRS-J-WJ-FL2), you get complete control over your axle placement and alignment, ensuring a smoother, more predictable ride.
