This is a rear wheel carrier concentric bushing (control arm mount – big size) made as a stock (OEM-style) replacement for the original Porsche rear hub mounting bushes. It conforms to stock dimensions and material properties, delivering reliable performance consistent with factory standards.

The concentric bush sits between the rear wheel carrier (hub) and the control arm mounting point. It absorbs vibrations, reduces unwanted movement in the suspension, and maintains correct wheel alignment geometry under normal driving conditions. By securely locating the hub relative to other suspension members, it helps ensure stable handling and tyre contact with the road.

As part of the rear suspension assembly, this bush allows controlled rotation of the wheel carrier while reducing noise, harshness, and vibration. Its stock-level stiffness provides a balance of comfort and stability suitable for everyday road use, maintaining proper suspension dynamics without the harsher feel of sport or motorsport variants.

Over time, suspension bushes can age, harden, or deteriorate due to heat, load cycles, and environmental exposure. Worn bushes may allow excess play in the rear wheel carrier, leading to:
•  Clunking or knocking noises from the rear suspension
•  Loose or imprecise handling Uneven tyre wear
•  Misalignment of the rear wheel carrier
Replacing worn bushes with a stock-version concentric bush restores proper support at the hub mount, helping maintain smooth ride quality, stable steering response, and predictable rear suspension behaviour.

Consider replacing this rear wheel concentric bush if you notice any of the following:
•  Play or looseness in the rear wheel assembly
•  Knocking or clunking noises from rear suspension
•  Vehicle feels unstable or vague in rear end handling
•  Physical signs of rubber degradation, cracking, or splitting
•  During rear suspension service, alignment work, or control arm replacement

The PR52048P is a motorsport-grade concentric monoball unit designed for the rear wheel carrier (hub) control arm mount on Porsche 991 vehicles. Built with precision engineering and performance materials in Europe, it replaces the conventional rubber suspension bush with a hardened spherical bearing for maximum control and responsiveness.

Installed at the rear wheel carrier to control arm mount, the monoball reduces compliance that is inherent in traditional rubber bushes. By replacing rubber with a spherical bearing, it ensures the hub remains precisely located relative to suspension loads - even under high lateral and longitudinal forces. This significantly improves handling consistency and repeatability during aggressive driving.

Rubber suspension bushes, while comfortable for everyday driving, can flex and deform when subjected to high cornering forces or track load. This compliance can lead to:
• Reduced suspension precision
• Vague handling at the limit
• Unwanted changes in camber and toe settings under load.

This motorsport monoball replaces that compliant interface with a hardened spherical bearing, virtually eliminating bush flex and delivering a more direct, predictable response - ideal for track days, competition use, and drivers who demand precise rear-end control.

When to replace
Consider this upgrade or replacement if:
•  You are building a track-focused suspension setup
•  You experience unwanted rear wheel carrier movement at high loads
•  You want to reduce compliance and improve mechanical feedback
•  Rubber bushes are worn, cracked, or allowing excessive play

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.
