Description

The CUSCO Rear Suspension Arm / Rear Pillow Ball Bushing is a performance-focused suspension upgrade designed to replace the factory rubber bushings at the rear mounting points of the rear suspension arms with high-rigidity pillow ball (spherical) bushings. This targeted upgrade eliminates compliance in a critical area of the rear suspension, enhancing rear-end stability, cornering precision, and overall chassis feedback for drivers seeking maximum control during spirited and competitive driving.

Product Highlights

🎯 Precision Pillow Ball Bushing Replacement
Replaces the compliant factory rubber bushings at the rear mounting locations of the rear suspension arms with rigid spherical pillow ball bushings, providing a direct, zero-deflection connection between the suspension arm and chassis.

⚡ Enhanced Rear Suspension Stability & Response
By eliminating bushing flex at these key rearward mounting points, this upgrade delivers immediate and precise rear suspension reaction, reducing unwanted lateral movement and improving rear-end composure during cornering, acceleration, and braking.

🔧 Direct OEM Bushing Replacement – Complete Set
Engineered as an exact, bolt-in replacement for the targeted factory bushings. The set includes two bushings (left and right) to ensure balanced and symmetrical suspension performance across the rear axle.

🏁 Competition-Grade Suspension Tuning
Ideal for track, autocross, and high-performance driving where minimizing all forms of suspension compliance is critical for optimal tire contact, predictable handling, and consistent lap-time performance.

⚙️ Maintains Proper Suspension Articulation
While eliminating unwanted lateral and longitudinal flex, the spherical design allows for the necessary rotational articulation of the suspension arm, preserving correct geometry without the drawbacks 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 precision task that must be performed by a qualified shop with proper suspension tools. A full rear-wheel alignment is mandatory after installation.

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

🎯 Recommended for Dedicated Performance & Track Builds
Best suited for vehicles used primarily in competitive environments or by drivers who prioritize ultimate suspension response and chassis control over ride comfort. For dual-purpose street builds, consider CUSCO’s urethane bushing alternatives.
