Keep your Mustang’s engine under control when the power comes on hard.
The Granatelli GM-MM0507 Heavy-Duty Motor Mounts are designed for 2005–2014 Ford Mustang applications where the factory hydraulic mounts can allow excessive engine movement during hard acceleration, aggressive shifting and performance driving.
By creating a more rigid connection between the engine and chassis, these mounts help reduce engine twist, improve drivetrain stability and transfer power more efficiently—making them an excellent upgrade for modified street cars, drag cars, road-course builds and high-horsepower Mustangs.
GRANATELLI CHASSIS PERFORMANCE
LESS ENGINE MOVEMENT. MORE CONTROL.
Control unwanted engine twist so the drivetrain stays more stable during launches, shifts and aggressive acceleration.
|
LESS TWIST
Helps reduce excessive engine movement under hard acceleration and shifting.
|
MORE CONTROL
Creates a more stable connection between the engine, drivetrain and chassis.
|
BETTER TRANSFER
Helps keep more of the engine's effort focused on moving the vehicle forward.

Why Upgrade Your Mustang Motor Mounts?
Factory hydraulic motor mounts are designed with comfort and vibration isolation in mind. Under hard acceleration—or as the original mounts begin to wear—the engine can move excessively inside the chassis.
Granatelli heavy-duty mounts are designed to significantly reduce that movement. The result is a more controlled drivetrain, improved stability during hard acceleration and a more direct performance feel from the engine through the chassis.

Important Fitment Notice: Part #GM-MM0507 is designed for 2005–2014 Ford Mustang applications. Fitment varies by engine and submodel. Verify your Mustang's model year, engine and existing motor-mount configuration before ordering.
Performance Note: Heavy-duty polyurethane motor mounts provide a more rigid engine-to-chassis connection than soft factory hydraulic mounts. Depending on the vehicle and other modifications, additional engine vibration may be felt inside the cabin. This is normal for a performance-oriented motor mount.
