Description

The CUSCO Rear Upper Control Arm Pillow Ball Bushings are a precision suspension upgrade designed to replace the factory rubber bushings in the rear upper control arms with high-rigidity pillow ball (spherical) bushings. This targeted modification eliminates compliance at a critical suspension mounting point, enhancing rear-wheel alignment stability, cornering precision, and overall chassis feedback for superior handling performance during aggressive and competitive driving.

Product Highlights

🎯 Precision Pillow Ball Bushing Replacement
Replaces the soft factory rubber bushings in the rear upper control arms with rigid spherical pillow ball bushings, establishing a direct, zero-deflection link between the control arm and chassis for absolute suspension precision.

⚡ Improved Rear-Wheel Alignment Stability
By eliminating bushing flex in the upper control arms, this upgrade maintains consistent rear-wheel camber and toe settings under load, leading to more predictable handling, better tire contact, and enhanced cornering stability.

🔧 Direct OEM Bushing Replacement – Complete Set
Engineered as an exact replacement set for the factory upper control arm bushings. Includes two bushings (left and right) to ensure balanced performance and symmetrical suspension behavior.

🏁 Competition-Grade Suspension Control
Ideal for track, autocross, and high-performance driving where maintaining precise rear suspension geometry under dynamic loads is critical for optimal grip, traction, and lap-time consistency.

⚙️ Maintains Necessary Suspension Articulation
While eliminating unwanted lateral and longitudinal deflection, the spherical design permits the required rotational movement of the control arm, preserving proper suspension travel and geometry without the vagueness of rubber compliance.

Installation & Performance Notes

🔧 Professional Pressing & Alignment Required
Installation requires pressing out the original rubber bushings and pressing in the new pillow ball bushings—a task that must be performed by a qualified suspension specialist with proper tools. A full rear-wheel alignment is mandatory after installation.

⚠️ Increased NVH (Noise, Vibration, Harshness)
As with any spherical bushing upgrade, expect a noticeable increase in road noise and vibration transmission into the cabin. This is an intentional trade-off for the gain in suspension precision and chassis communication.

🎯 Recommended for Serious Performance & Track Applications
Best suited for vehicles used in competitive environments or by drivers who prioritize ultimate suspension response and alignment stability over ride comfort. For street-focused builds, consider CUSCO’s urethane bushing alternatives.
