This torque converter is designed for the muscle car and street rod crowd with enough stall to launch the car and efficient enough to drive everyday. It is built to withstand up to up to 500-850hp on muscle. It has many of the same design features of our Bullet Race Series torque converters with the ability to drive them on the street. When you want to burn your tires and blow your competition away this is the only converter to have in your car.

Specific stator and turbine modifications perfectly match the Hemi's torque curve. There is literally no loss of driveability. While many torque converter manufacturers are focused simply on stall-speed (the amount of torque converter slip), Pro-Torque understands that torque multiplication and efficiency are the key to performance. Reliability is increased as well as performance.
