The 4 mm aluminum motor plates for the Pro Series Magnum 272R™ transmission are thicker than the stock plate for increased rigidity and high-horsepower applications. Made from tough 6061-T6 aluminum and brilliantly anodized in eye-catching colors, they add strength and style to your vehicle. Includes 3x10 mm screw and washers (2). (Does not fit standard Magnum 272™ transmission)
