Rear wheel carrier concentric monoball kit.
1 kit required per car

Monoball Cartridges replace factory rear wheel carrier bushings with hardened-steel spherical bearings. Spherical bearings allow free motion on multiple axis and eliminate deflection associated with rubber, resulting in more precise holding of toe and camber.

High tolerance machined housing allow for simple press fit installation. Correct spacers ensure proper fitment.

Weather Sealed
Monoball housing and spacers are hard anodized for protection. Our proprietary rubber seals keep the precision bearing from road contaminates for extended life of the product.

The kit includes two monoball bearings… one for each rear wheel carrier

Rear wheel carrier concentric bush / rear wheel hub - shock absorber mount - bushing (small).
Sport version. This replacement bushing is designed and manufactured in Europe using a stiffer rubber compound and is perfect for sporting applications. This bushing is part of rear wheel hub / rear wheel carrier assembly – OE ref no. 99133111103 / -104 / -105 and 99133111203 / -204 / - 205.
SOLD Individually. 2pcs required per car.

Concentric bushes wear with age and mileage. Hardened, cracked, or deteriorated bushes can allow excess movement in the rear wheel hub, which may cause:
• Clunking or knocking noises from the rear suspension,
•  Increased body roll or vague handling,
•  Uneven tyre wear,
•  Reduced stability under braking or cornering.

The sport version PR52053P uses a stiffer rubber compound than stock to provide more precise control while still offering compliant ride quality - making it ideal for drivers who want sharper feel without jumping to full motorsport components.

Replace this rear wheel carrier concentric bush if you notice any of the following:
•  Noticeable play or looseness in the rear hub under load
•  Clicking/knocking sounds from the rear during acceleration, braking, or over bumps
•  Rear handling feels imprecise or soft
•  Visual signs of cracks, splits, or material deterioration
•  You’re upgrading to sportier suspension behaviour

This is an advanced concentric monoball unit developed as a motorsport-spec replacement for the OE rear wheel carrier concentric bushing used on Porsche 991 vehicles. Unlike standard rubber bushes, the monoball features a spherical bearing design that provides minimal deflection, outstanding durability, and direct suspension feedback.

The rear wheel concentric monoball replaces the soft rubber bush at the connection between the wheel carrier and suspension arm/strut mount. It completely eliminates compliance in this joint, allowing for direct transfer of suspension loads with minimal movement, which enhances alignment precision and stability under high-load cornering, braking, and acceleration.

Traditional rubber bushes are designed for comfort and everyday driving. Under high lateral loads, they can deflect, leading to:
•  Slight rear wheel misalignment
•  Vague handling response
•  Reduced feedback to the driver

This motorsport monoball eliminates this compliance by using a precision spherical bearing assembly that holds the rear wheel carrier in a fixed position relative to the control arm. This enhances steering precision, improves feedback, and delivers confidence-inspiring control on track or spirited road driving.

This motorsport version is ideal for:
•  Track days and competitive events
•  Aggressive driving
•  Suspension setups where reduced compliance is critical
•  Drivers seeking maximum handling precision

When to replace. Consider upgrading to monoballs if you experience:
•  Excessive deflection or “mushy” feel in the rear suspension
•  Delayed response under hard cornering
•  Vague rear end feel during acceleration or braking
•  You’re rebuilding or upgrading suspension for track use
•  High mileage or worn stock bushes showing play


•  The motorsport version delivers significant gains in precision but may transmit more noise and harshness than stock or sport bushes — this is normal for competition-oriented parts.
•  Sold individually — 2 per vehicle recommended for balanced installation.
