Why Replace It, Engine mounts are crucial for:
Locating and supporting the engineAbsorbing vibration and engine torque under acceleration, braking, and corneringWhen this mount deteriorates or fails, you can expect, Increased vibration transmitted to the cabin, steering, or pedalsClunks, bangs, or loud noises during acceleration, deceleration, or gear changes from engine movement against the chassisVisual signs such as leaking black fluid from the mount, sagging of tailpipes (due to dropped mounting), or visible damage to rubber or metal componentsCommon Failure Causes
Age-related rubber degradation: over time, rubber hardens, cracks or de-bonds, causing loss of damping and allowing engine movementFluid leakage (hydraulic version): loss of damping fluid due to seal failure accelerates failureFluid contamination: oil, coolant, or other contaminants degrade the rubber materialVehicle abuse or stress: aggressive driving, hard launches, or previous accidents can warp or break mountsWorn or cracked brackets: even if the rubber is intact, the aluminium bracket can be damaged or corroded, reducing effectiveness

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.

                    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.
