Information
Rear wheel carrier concentric monoball / rear wheel hub - control arm mount - monoball (big),
Motorsport / Racing version. This monoball is perfect for all track oriented race enthusiasts. This monoball 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.
Fits:
Porsche 991 2012 >>
Porsche 991 Turbo 2012 >>
Fits number 1 on the diagram.
Part highlighted in green on the diagram.
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
