2004-2005 Duramax Diesel Engine Brake (55447)

Fits

The new all-electronic Banks Brake offers total safety and a whole lot more for when you and your Duramax are heading over those big hills! How Does The Banks Brake Work? It works by modulating systems already found on the vehicle with no mechanical additions. And its level of braking power and intensity is completely user-selectable at the turn of a switch. It's extremely easy to install, even easier to use. Towing a heavy load and dealing with steep downhill grades can be scary. Under those conditions, things can happen in a hurry. With its easy-to-use switch control, you set the braking intensity and Banks Brake does the rest.
