The World's First all-electronic Braking System for the Duramax to keep your Duramax working hard for you. A revolutionary approach to exhaust braking, Banks patented new SpeedBrake does what no brake has done before. The world's first all-electronic braking system, SpeedBrake achieves maximum braking power by intelligently modulating systems already found on the truck. SpeedBrake manipulates the variable geometry turbine vanes in concert with deliberate gear selection and torque converter clutch application to deliver not just total hill-taming stopping power but also peace of mind. Hands (and feet) free, and totally automatic, SpeedBrake lets you set your desired downhill speed and it does all the rest.
