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 & 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 #55449.

FEATURES & 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!)

Only Banks SpeedBrake slows you down!

It's all automaticImagine setting your "comfort zone" and cutting downhill speed by nearly 80% without even touching the brake pedal, keeping your brakes cool and ready for emergencies should they arise. The SpeedBrake increases the stopping power of your truck and extends the service life of your brakes, and does so while maintaining your sanity.

That's what we thought too, but the other products on the market provide inadequate braking power and actually allow your speed to increase as you plummet faster and faster downhill. With the competition's poor performing product, you are forced to use your truck's brakes and manually shift your transmission in an effort to gain lost confidence.

The SpeedBrake is an all-electronic mastermind of braking technology. Plug-in connection makes for a clean, simple installation without cutting or tapping into vital wire harnesses. There's no crawling under the truck to cut up your exhaust system and no mechanical "adjustments" necessary to ensure its function. SpeedBrake uses the truck's own components to give you the safety you need when towing, so there are no added mechanical parts to second guess.

With the SpeedBrake there's no competition and no compromise. This smart device becomes an active component of your vehicle, constantly monitoring and adjusting systems to achieve the speed setting you command. With its patented technology, the SpeedBrake controls your transmission's shifting, locks and unlocks the torque converter, and infinitely varies the VG turbo's vanes to hold your set speed and maximize stopping performance to ensure that you have safety and confidence for the long haul. Watch it all happen as the Banks iDash keeps you informed by displaying important parameters and on-screen alerts you set. And... it's also an OBD-II scan tool. - Now That's Smart!

OK, Test Time!
