112 Truck Crashes Caused by Brake Failure?
According to the US Department of Transportation, there are 41,000 truck crashes every year caused by brake failure? That's 112 every single day here in America alone!
If you drive a truck, like a Ford F-series, GMC, Chevy, or Dodge Cummins, then you know how scary it can be when you're hauling a heavy load and you're driving on steep hills. Regular brakes just don't cut it. That's why Big Rigs and newer trucks all have additional braking systems to give them superior control. These diesel exhaust brakes, electric exhaust brakes, or inline exhaust brakes are generally not standard on trucks before 2015.
The good news is that now you can get superior braking control on your Ford, Chevy, GMC, or Dodge truck with the best-in-class Sentinel Exhaust Brake System™ by Bundy Motors. It is the only electric diesel exhaust brake system on the market that not only has a genuine Lifetime Guarantee (with no small print or “exceptions”), and can literally be installed in less than an hour!

the Sentinel Exhaust Brake System™ Works.
Aftermarket exhaust brakes are used to slow down a truck without using the traditional axle brakes. Instead, diesel exhaust brakes work by restricting the exhaust flow, causing exhaust back pressure to build inside the engine cylinders, which then slows down the truck through the power train. Electric exhaust brakes increase safety and drivability by slowing down the truck over long or short periods of time without applying the traditional brakes. They also lower overall vehicle maintenance cost and minimize damage to the traditional axle braking system.
Our inline exhaust brakes takes less than an hour to install and have a unique design to control proper back pressure without using unreliable modules. They also costs typically 20% less than our competitor's diesel exhaust brakes. Oh... and they sound great too!
If you have a diesel truck, and you actually use it to haul things, then you need the Sentinel Exhaust Brake System™ by Bundy Motors!
