300M 2-Piece Output Shafts
These new heavy duty output shafts feature a unique 2-piece design with an extended bearing
surface. They are gun-drilled to save weight with no governor or speedometer support. A “must have” for your T-400 when high horsepower meets heavy weight or rear gear is numerically
low. This strong, affordable option is easily installed and can be purchased outright or as an
upgrade option in your next ATI 400 transmission.
