2006-2007 6.6L LLY/LBZ GM Duramax
Exhaust Brakes | Variable Vane Exhaust Brakes


While its true that the Allison transmission is capable of handling some serious loads while descending a hill with its automatic downshift feature, it still leaves something to be desired, especially when truly using the truck to its full potential.  This is why we offer several solutions to help you get SAFELY to the bottom of the grade.  At Diesel Power Products we carry exhaust brakes from the biggest and best names in the diesel exhaust brake industry.  BD Engine Brake, PacBrake, and Banks have long been recognized as the innovators when it comes to light duty exhaust brakes. 

Aside from the traditional butterfly valve style exhaust brakes, we also offer several models of Variable Vane Exhaust Brakes.  These brakes take a unique approach to exhaust braking, essentially taking control of the factory variable vanes built into the factory turbo to create a similar type of retarding power.  For those familiar with the 6.7L Cummins factory exhaust brake, the addition of an aftermarket device onto your Duramax will create the same effect.  Overall, these types of brakes are much simpler to install and less expensive than a traditional in-line exhaust brake.

As always, if you have any questions about which brake is right for you and your truck, do not hesitate to give us a call or send an e-mail to [email protected] and we would be happy to assist.
