Banks' revolutionary design produces stronger braking power than other exhaust brakes. The large-bore housing, streamlined to increase airflow and diffuse exhaust, adds to engine power when Banks Brake is inactive. Banks engineered in a timed valve closure rate to prevent backpressure spikes common to other exhaust brakes and provide smooth operation. Every unit is factory tested and never requires calibration.
