Product Overview
This precision-engineered engine mount securely holds your engine in place while absorbing vibrations and road shocks. Manufactured from high-grade steel and vibration-resistant rubber or hydraulic components, it ensures long service life even under demanding driving conditions.

Key Features & Benefits

  • OEM-equivalent performance – Direct replacement for part number 9A137502322.
  • Enhanced vibration isolation – Reduces cabin noise and harshness for a smoother, quieter drive.
  • Durable construction – Corrosion-resistant housing with high-quality bonding for long life.
  • Precision fit – Matches factory specifications for fast, trouble-free installation.
  • Improves ride quality and handling – Maintains correct engine position and drivetrain geometry.
  • Prevents costly damage – Reduces stress on exhaust systems, hoses, and electrical wiring.


Symptoms of a Worn or Failing Engine Mount - 
If your engine mount is worn, you may notice:

  • Excessive vibration or shaking at idle or during acceleration.
  • Clunking or knocking noises when shifting gears or accelerating.
  • Engine movement or rocking under load.
  • Visible cracks or leaks in the rubber or hydraulic fluid.
  • A sagging or misaligned engine in the bay.

These symptoms suggest it’s time for replacement before further damage occurs.

Common Causes of Failure - Engine mounts naturally wear out due to:

  • Age and fatigue (rubber hardens, cracks, or loses elasticity).
  • Oil or coolant leaks that deteriorate the rubber.
  • Harsh driving or torque loads from aggressive acceleration.
  • Incorrect installation or over-tightened fasteners.
  • Corrosion on the mounting brackets or bolts.


Why Replace an Engine Mount? - 
Replacing your mount restores stability, comfort, and safety.

  • Prevents engine movement that can damage hoses or wiring.
  • Reduces vibration and noise inside the cabin.
  • Maintains alignment of the drivetrain and transmission.
  • Avoids premature wear on suspension and steering components.
  • Restores factory ride comfort and performance feel.

 

Quality You Can Trust
All mounts are manufactured to OEM or higher standards, tested for vibration resistance, and backed by our quality guarantee. Replace both left and right mounts if necessary for balanced support and maximum longevity.

About Engine Mounts

Engine mounts, also called motor mounts, are critical components of your Porsche, securing the engine to the chassis and absorbing vibrations during operation. Traditionally, rubber has been the go-to material for these mounts, but polyurethane is gaining popularity due to its enhanced performance and durability compared to rubber.

Polyurethane motor mounts excel at absorbing vibrations, ensuring a smoother and quieter ride, benefiting both driver and passengers. Although they are initially more expensive than rubber mounts, their longer lifespan makes them more cost-effective over time, reducing maintenance and replacement expenses.

In high-performance vehicles like Porsches, motor mounts face extreme stress, vibrations, heat, and pressure. Uprated polyurethane motor mounts provide additional benefits by limiting engine movement, enhancing engine stability during acceleration and gear shifts, and offering improved gear engagement, thus protecting gearboxes and shafts.
