Engine mounts isolate vibration while securely supporting the engine and gearbox within the chassis. Over time, the original rubber mounts can soften, crack, collapse, or separate due to heat, oil contamination, and age. This allows excessive engine movement, affecting gear changes, drivetrain alignment, throttle response, and overall driving refinement. Replacing worn mounts with this Heavy Duty RS Version kit restores proper engine location and provides enhanced drivetrain stability. This OE Match kit is ideal for routine maintenance, performance upgrades, repairs, and Porsche restoration projects.
What This Product Does:
- Securely supports the engine within the chassis.
- Reduces excessive engine and drivetrain movement.
- Improves drivetrain stability during acceleration and braking.
- Enhances gearshift precision by maintaining engine alignment.
- Offers increased stiffness compared to standard engine mounts.
- Replaces worn, collapsed, or deteriorated original mounts.
- Provides an OE-style fit and dependable quality.
Symptoms Of Wear Or Failure:
- Excessive engine movement under acceleration or braking.
- Increased drivetrain vibration.
- Clunking or knocking from the rear of the vehicle.
- Poor or inconsistent gear selection.
- Sagging or collapsed engine mounts.
- Cracked, split, or oil-contaminated rubber.
- Visible separation of the rubber from the mount housing.
- Age-related deterioration of the original mounts.
Why Replacement Matters:
- The engine mounts play a vital role in supporting the engine while isolating vibration and controlling drivetrain movement. Worn or collapsed mounts allow excessive engine movement, which can affect handling, gearshift quality, drivetrain alignment, and place additional stress on surrounding components.
- Replacing the original mounts with this Heavy Duty RS Version kit restores secure engine support while providing the firmer control associated with the RS specification. The result is improved drivetrain stability, more precise gear changes, and increased confidence during spirited driving. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match engine mount kit provides the correct fit, dependable quality, and long-lasting durability, making it an excellent choice for Porsche maintenance, performance upgrades, repairs, and restoration projects.

OEMatch Engine Mounts — Durability, Sealing, Performance
Engine mounts secure the engine to the chassis while damping vibration and maintaining drivetrain alignment. For Porsche models, OEMatch Engine Mounts are selected to restore stability and reduce transmitted vibration, helping to preserve handling precision and protect connected components during everyday and spirited use.
Available Types
- High-grade rubber engine mounts
- Performance polyurethane mounts
- Reinforced composite mounts
- Hydraulic or fluid-filled mounts where specified by model
Understanding OEMatch Engine Mounts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine mounts.
OE (Original Equipment) refers to parts matching original specifications for the engine mounts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine mounts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Engine mounts hold the engine and transmission in the correct position while isolating vibration from the cabin and drivetrain. Different constructions balance isolation and control: rubber absorbs vibration, polyurethane can offer firmer control, and reinforced composites aim to combine strength with damping. OEMatch focuses on engine-mount items selected for Porsche applications to support correct fit and function.
Benefits Include
- Restores drivetrain stability and precise engine positioning
- Reduces vibration and harshness for improved cabin comfort
- Protects hoses, wiring and exhaust connections from excess movement
Why Engine Mounts Wear and Fail
- Material fatigue from repeated heat cycling and age
- Oil or fluid contamination that softens rubber or polymer parts
- Excessive engine torque or vibration, especially on modified or high-mileage engines
- Corrosion or cracking in metal brackets and mounting hardware
The Importance of Replacing with OEMatch Engine Mounts
Replacing worn engine mounts maintains accurate engine positioning and reduces secondary stresses that can accelerate wear on hoses, wiring, exhaust connections and transmission mounts. Timely renewal helps preserve the handling balance and refinement expected from a Porsche and avoids secondary repairs caused by excessive engine movement.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Made to original-spec dimensions for consistent performance
- Compatible with factory systems and sensors where required by model
