The Mount for the Porsche 997 Generation 1 and Generation 2 Coupe (Porsche product code 99737504908) serves as a critical component that secures the engine to the vehicle's chassis. It helps to absorb vibrations and impacts from the engine during operation, maintaining stability and ensuring a smooth ride. This particular engine mount is designed to meet the specific structural and performance requirements of the Porsche 997, providing durability and reliability for both everyday driving and performance enhancements. Proper functioning of the engine mount is essential for optimal engine performance and to minimize wear on other related components.

• Position on Vehicle: Front engine mount assembly (left OR right side) – front of the engine block, attaching to the chassis via mount bracket.
• Cross-Reference / Alternative Numbers: OEM: 997 375 049 08; also superseded from 997 375 049 04 and 997 375 049 06 in earlier listings.
•  Applications: Use this mount when original mount shows signs of failure — to restore engine stability, reduce vibration, maintain correct engine alignment and safeguard ancillary components.

An engine mount  plays a vital role in stabilising the powertrain and isolating engine-borne vibration from the cabin and chassis. Over time the hydraulic fluid, rubber bushings or bonding will degrade, causing increased engine movement, vibration, noise or premature wear of transmission and drivetrain components. Replacing a suspect mount restores comfort, handling precision and engine/gearbox alignment.

When and why to replace:
• Noticeable engine vibration, rumble or harshness in the cabin or at idle.
• Visual signs of mount wear: cracked rubber, leaking fluid, broken bracket.
• After engine removal, major service or performance upgrades (making access easier).
• High-mileage vehicle where original mounts are likely ageing and losing damping capability.
• Preventive replacement before mount failure protects drivetrain components and avoids costly collateral damage.

For the revision of your Porsche engine, we offer this engine mount. The flange surface with your cantilevers to the mounting axis allows a secure and at the same time easily accessible attachment of the engine to a rolling engine stand. Alternatively, you can use the engine mount to mount the engine to a workbench using a bearing block. We have the engine stands for all classic Porsches with and without a mounting stand in our program.

Hexagon Nut M10.
Special Order item
PAF008868
Product Information
Product Information

The M10 hex nut is a versatile, high-strength fastener used across a wide range of Porsche models and assemblies. From suspension links to engine brackets, exhaust components, body fittings, and drivetrain hardware, this M10 nut ensures secure fastening and reliable torque retention where precision and durability are essential.

Manufactured to meet stringent automotive engineering standards, this nut provides excellent resistance to vibration, temperature variation, and long-term mechanical stress. Whether carrying out routine maintenance, restoring a classic model, or replacing aged hardware, this M10 hex nut is an essential component for maintaining structural integrity and correct assembly torque throughout your Porsche.

What Do M10 Hex Nuts Do?

M10 hex nuts are critical fasteners used to clamp, secure, and stabilise components throughout the vehicle.

Core Functions:
Provide secure threaded fastening in suspension, engine, exhaust, and chassis assemblies.
Maintain clamping force during high-load or high-vibration conditions.
Support correct alignment of mechanical components.
Ensure safety and structural strength across various mounting points.
Maintain torque settings essential for performance and reliability.

Why Do M10 Hex Nuts Fail?

Over time, fasteners experience wear, stress, and environmental exposure that can compromise their performance.

Common Causes of Failure Include:

  • Corrosion from moisture, salt, or road debris.
  • Thread wear from repeated installation or overtightening.
  • Loss of clamping force from heat cycling or vibration.
  • Rounded edges caused by incorrect tools or age.
  • Metal fatigue leading to cracking or deformation.

A compromised nut can lead to loose fastenings, misalignment, and in some cases, component damage or safety issues.

Why Replace or Upgrade Your M10 Hex Nuts?

Replacing aged or worn nuts ensures proper fastener tension and maintains the reliability of the components they secure.

Key Benefits:

  • Restores proper torque retention and fastening integrity.
  • Prevents vibration-related loosening and component failure.
  • Ensures corrosion resistance for long-term durability.
  • Suitable for multiple Porsche applications across generations.
  • Ideal for restoration projects, rebuilds, and preventative maintenance.
  • Precision-engineered for a perfect, secure fit.

Fresh hardware is particularly important when servicing high-stress areas such as suspension mounts, exhaust fixtures, and drivetrain assemblies.

About Engine Mounts

Replacement Engine Mounts – Stability, Comfort, and Performance for Porsche Models

Engine mounts are the unsung heroes of your Porsche’s drivetrain, securing the engine to the chassis while absorbing vibration and maintaining precise alignment. Over time, these components can degrade from constant heat, torque, and road stress — affecting ride quality, handling, and drivetrain performance.

At Design911, we supply a wide selection of precision-engineered replacement engine mounts designed to the highest performance standards. Manufactured from high-grade rubber, polyurethane, or reinforced composite materials, these mounts provide the perfect balance of vibration isolation and structural support.

Whether you’re restoring a classic air-cooled model or maintaining a modern 911, manufacturer-quality mounts ensure smooth operation, improved comfort, and precise drivetrain alignment under all conditions.

What Do Engine Mounts Do?

Engine mounts secure the engine and transmission to the vehicle’s chassis, minimising movement while isolating vibrations that would otherwise transfer into the cabin.

Core Functions:

  • Securely position the engine and transmission within the chassis.
  • Absorb vibration and torque movement, improving comfort and handling.
  • Maintain drivetrain alignment for optimal power transfer.
  • Reduce stress on components such as hoses, wiring, and exhaust connections.

Well-fitted engine mounts preserve your Porsche’s distinctive refinement and handling precision, especially under high load or spirited driving.

Why Do Engine Mounts Fail?

Due to constant exposure to torque, heat, and vibration, engine mounts naturally degrade over time. Worn or broken mounts can lead to excessive engine movement, clunking noises, and vibration inside the cabin — symptoms that should never be ignored.

Common Causes of Engine Mount Failure Include:

  • Material fatigue from age or repeated heat cycling.
  • Oil contamination, softening rubber or polymer components.
  • Excessive engine torque or vibration, especially on tuned or high-mileage engines.
  • Corrosion or cracking in metal brackets or hardware.
  • Improper installation leading to uneven stress and premature wear.

Failing mounts compromise performance and comfort, causing drivetrain misalignment and potential damage to surrounding components.

Why Replace with Precision-Engineered Engine Mounts?

Upgrading to high-quality replacement engine mounts restores the stability, refinement, and handling balance your Porsche was designed for. Precision-engineered mounts ensure reliable load distribution, vibration damping, and improved driving comfort.

Key Benefits:

  • Restores drivetrain stability and precise engine positioning.
  • Reduces vibration and harshness, improving cabin comfort.
  • Enhances throttle response by limiting engine movement.
  • Protects critical components from stress and misalignment.
  • Available in rubber or performance polyurethane for tailored ride feel.
  • Perfect fitment across Porsche models — air-cooled, turbocharged, or hybrid.

Whether you’re maintaining daily drivability or preparing for track use, replacement mounts deliver the durability and control your Porsche deserves.

Highlights:

  • Precision-engineered replacement engine mounts for all Porsche models.
  • High-grade rubber, polyurethane, or reinforced construction.
  • Improves handling, comfort, and vibration isolation.
  • Direct-fit compatibility for easy installation and perfect alignment.
  • Ideal for rebuilds, performance upgrades, or preventive maintenance.
  • Restores driving dynamics and comfort in classic and modern Porsches.
