Summit Racing™ Automatic Transmission Drum Assemblies

Most racing is done using a modified version of a factory automatic transmission. Today's high-tech, high-horsepower engines transfer incredible amounts of torque through these transmissions to the driveline. Summit Racing™ automatic transmission drums improve performance, reliability, and holding power. Whether by using beefier designs than factory parts, by adding larger/extra clutches, or using lighter, stronger materials, you'll get down the track and keep going rounds when you include Summit Racing™ transmission drums in your build.
