Powerflex Black Series - Designed for the Track - Ready to Race - Engineered to be the best.
Powerflex Black Series bushes are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material.
If your requirements are purely for the ultimate in handling and chassis performance then Powerflex Black Series are unique, offering the most precise and accurate alignment for your chassis.
Replacing your car rubber suspension bushes with Polyurethane Suspension Bushes will give you:
- Better road holding
- Constant steering geometry
- Increased tyre life
- More responsitive steering
- Longer service life of suspension components.

Information
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 >>
Diagram ref no 7
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.
• 8R0505311F – Rear lower control arm / trailing arm (Left side)
• 8R0505312F – Rear lower control arm / trailing arm (Right side)
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.

Information
Rear Lower Control Arm Bushing.
The Rear Lower Control Arm Bushing (FRONT) is a high-quality suspension bushing designed to restore correct mounting and controlled movement of the rear lower control arm on compatible Porsche vehicles. This bushing sits between the control arm and the chassis/subframe, acting as a flexible joint that absorbs road vibration while allowing the suspension to articulate smoothly under braking, acceleration, and cornering loads.
Sold Each, x2 Required Per Car.
Fits:
Porsche 95B.1 Macan 2014 - 2018
Porsche 95B.2 Macan 2019 - 2021
Porsche 95B.3 Macan 2022 >>

Over time, suspension bushings can deteriorate due to age, heat, road contamination, and repeated flexing. A worn rear lower control arm bushing can lead to clunking noises, unstable handling, uneven tyre wear, and difficulty maintaining proper wheel alignment. Replacing the bushing helps return suspension geometry to factory condition, improving comfort, stability, and overall driving confidence.
Symptoms Of Worn Or Failed Rear Lower Control Arm Bushing:
Noise & Vibration
Handling & Stability Issues

Replacing the bushing helps return suspension geometry to factory condition, improving comfort, stability, and overall driving confidence.
What This Product Does:
- Acts as the pivot point between the rear lower control arm and subframe
- Absorbs vibration and road shock for a smoother ride
- Maintains correct suspension geometry and alignment
- Helps control wheel movement under load (acceleration, braking, cornering)
- Reduces noise, harshness, and vibration transmitted to the cabin
Symptoms Of Worn Or Failed Rear Lower Control Arm Bushing:
Noise & Vibration
- Clunking, creaking, or knocking over bumps
- Vibration through the floor or rear of the vehicle
Handling & Stability Issues
- Wandering or unstable rear end
- Poor cornering response
- Braking pull or imbalance
Wear & Alignment Problems
- Uneven or accelerated tyre wear
- Difficulty holding a wheel alignment
- Rear end “floaty” feel at speed
Visual/Physical Signs
- Cracks, splits, or visible degradation of the rubber material
- Play or movement at the bushing when pushed/pulled
Why Replacement Matters:
- Worn bushings allow uncontrolled movement in the suspension, which degrades stability, steering feel, and driver confidence—especially in corners or sudden manoeuvres.
- Proper bushings help maintain wheel alignment under load, reducing uneven tyre wear and extending tyre life.
- New bushings absorb shock and vibration more effectively, reducing harshness and noise transmitted to the cabin.
- Controlling unwanted movement helps prevent premature wear of control arms, ball joints, and other suspension parts.
