Did you know every day there are 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 Exhaust Brake Systems to give them superior braking control which 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 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!
RANCH INSPIRED, TESTED AND APPROVED!

Don't be that person at the bottom of the hill on fire, in a ditch or in an ambulance!

How the Sentinel Exhaust Brake System Works

Exhaust brakes are used to slow down a truck without using the traditional axle brakes. They 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. Exhaust brakes increase safety and drivability by slowing down the truck over long or short periods of time with out applying the traditional brakes. They also lowers overall vehicle maintenance cost and minimizes damage to the traditional axle braking system.

Our brake takes less than an hour to install and has a unique design to control proper back pressure without using unreliable modules. It also costs typically 20% less than our competitors brakes. Oh, and it sounds great too!

If you have a diesel truck and you haul things then you need the Sentinel Exhaust Brake System™ by Bundy Motors!

Fits On Almost Any Diesel Truck!!
