You’ve got a vehicle that can haul an enormous load with no problem, because you’ve added optimizations and upgrades to your engine, so you’ve got power that puts the stock truck to shame. Most likely, a lot of your upgrades come from Bully Dog, because you know this is the first name in diesel performance upgrades. When you haul these kinds of loads, it can really take a toll on your brakes, and you’re going through brake pads like they were napkins. You’ve got to keep things under control on those long or extremely steep inclines, though. You need a Bully Dog Exhaust Brake, because if you don’t get some backup for your friction brakes, you’re going to have your red hot brakes glaze over one of these days, and then you’re in a life threatening situation. This part uses the stock turbo, and it wires an electrical brake control right into your existing system. It uses your turbo’s warm up valve to create the braking action, and it works great. You’ve got a switch in the cab, so you only have it when you want it, and because it uses the parts you’ve already got to brake the vehicle, a Bully Dog Exhaust Brake is surprisingly inexpensive.
