While factory rubber bushings are designed to isolate engine vibration, their soft construction often results in drivetrain lash, vague throttle response, and inconsistent gear shifts—especially under hard acceleration. The Whiteline engine and transmission mount bushing set is engineered to stiffen the drivetrain, providing the rigidity needed for crisp power delivery and defined shifting. These bushings work in conjunction with original mounts to mitigate excessive rotation without the harshness of a solid mount.

• Improved Throttle Response: Reduces engine and transmission movement for more immediate power delivery to the wheels.
• Advanced Materials: Whiteline synthetic elastomer formulation is resistant to oil, grease, ozone, and weathering.
• Self-Lubricating: Internal grease reservoirs provide continual lubrication for optimum friction management.
• Extended Life: Includes extreme pressure molybdenum disulphide (LM) based grease to ensure long-term performance.
• Manufacturer Part Number: W93571
