The Sinister Diesel High Performance Motor Mounts reduce drivetrain movement under hard acceleration, deceleration and cornering. They allow the most efficient transmission of all available power to the ground and result in easier transitions from on and off throttle in daily driving and more accurate launches during drag racing. Sinister Diesel engine mount kits also improve reliability, as they can not tear apart over time and with abuse like OEM mounts.
