Rear trailing arm, Lower.
The Porsche Genuine OE Rear Lower Control Arms (Part Nos. 8R0505311F and 8R0505312F) are factory-engineered suspension components designed for the rear axle of the Porsche 95B Macan. Often referred to as rear lower control arms or trailing arms, these components connect the rear wheel carrier to the chassis and form an essential part of the vehicle’s independent rear suspension system.

Fits:

Porsche 95B.1 Macan 2014 - 2018
Porsche 95B.2 Macan 2019 - 2021
Porsche 95B.3 Macan 2022 >>

Each arm is supplied as a single genuine Porsche product (sold individually) and includes integrated suspension bushings to ensure proper articulation, durability, and vibration isolation.

The rear trailing arm functions as a pivoting link between the rear suspension subframe and the wheel hub assembly. It allows the rear wheels to move vertically over bumps while maintaining precise wheel alignment relative to the vehicle body.

By controlling suspension movement and absorbing loads from braking, acceleration, and cornering, the control arm contributes to stable handling, smooth ride quality, and consistent tyre contact with the road surface.

Functions & Technical Role
•  Wheel positioning: Maintains correct rear wheel alignment and suspension geometry
•  Suspension articulation: Allows controlled vertical movement of the wheel over uneven surfaces
•  Load distribution: Transfers forces from braking, acceleration, and cornering to the chassis
•  Integrated bushings: Reduce vibration and road noise while allowing smooth pivot movement
•  OE-engineered durability: Manufactured to Porsche specifications for long service life and precise fitment

Over time, control arm bushings can wear due to road impacts, vibration, and continuous suspension movement. When worn, drivers may experience:
•  Clunking noises from the rear suspension
•  Uneven tyre wear
•  Poor wheel alignment or vehicle pulling
•  Reduced handling precision and ride comfort

Replacing worn arms with genuine Porsche OE control arms restores the correct suspension geometry and maintains the Macan’s original driving dynamics.
