The World's First All-Electronic Braking System. 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.

U.S. PATENT NUMBERS: 6,652,414 B1 and 6,152,853

PLEASE NOTE: The Banks SpeedBrake must be used with an iDash DataMonster or SuperGauge (NOT INCLUDED). If you do not want to use the Bank iDash then check out our SpeedBrake with switch #55447.

FEATURES and BENEFITS: More effective braking than is possible with a simple valve assembly. Operating modes ON (Maximum braking: High, Med and Low strength settings), SPEED CONTROL (Maintains pre-selected target speed. Easy touch-screen control). Displays vehicle speed, current braking effort (relating to vane position), trans temp, engine coolant temp and much more. OBDII scan tool capability (reads/interprets/clears codes). System Status Indicator with on-screen alerts (excessive coolant or trans temps, for example). Easy, clean install (all-electronic design requires only a few simple underhood connections), no modifications to the exhaust system are needed. In testing, dramatically outperformed all competitive products in basic braking function (and nobody but Banks has anything like a Speed Control Mode!)

Avoid this handle if you use it
Color: Black, Size: Driver side
Good Product if you don't use it, terrible product if you do use it. The plastic it's made of is too flimsy and gets worse with heat. Installed this product and it only lasted a month and a half before the metal reinforcement plate ripped off the entire plastic handle assembly.

Fitment is decent
Color: Tan, Size: Passenger side
Overall a nice replacement color matched but the fitment was a little loose even though tightened well, where the end comes toward the top of the pillar it is loose and doesn't fit flush
