the change in technology as the newer truck models rolled out
of the plant, we at BD have changed as well to apply our over
20-years of braking technology to match. With the newer Chevy
Duramax engines, the change was already there, we just had to
utilize it for your engine retarding needs.
The same Garrett
variable vane turbo design is used in the 2006-up Duramax
engine to reduce turbo lag and increase power can also help
slow you down. BD utilizes the variable technology built into
the turbo by closing off the vanes while retarding creating
up to 35psi of back pressure. What does this give you? Ample
retarding horsepower to help maintain your speeds on descents
and curves giving you better control of your truck and load.
How do you use
it? While in Tow/Haul mode, switch BD’s EX-Brake on
and every time you let off the throttle it will close the
variable vanes in the turbo which develops exhaust back pressure
in the engines combustion chamber, creating resistance against
the piston from reaching top dead center.

close off the vanes which can create up to 130 retarding horsepower.

rotary switch offers three different modes included automatic
moderate and aggressive downshifting programs for the Allison
transmission to give better weight control. Exhaust braking
also works in Allison manual shift selections. The Ex-Brake
integrates with the cruise control to automatically accelerate
and decelerate to maintain vehicle speed.
great value for an quick-to-install exhaust brake. An easy job
for a handy man!
Easily and simply installs by plugging into existing factory
ports and by mounting the rotary switch on your dash. All of
these features in one package which with some competitors would
require two separate ones at nearly twice the price and twice
as long to install. Now that is value added engine retarding
at it’s engineered finest.
Is it hard on your truck? Not at all…
We have designed our brake to not make harsh downshifts into
lower gears that can cause tire “chirp” and drive
train strain. The exhaust brake is also firmware updateable
via the internet using your computer's USB connection and is
the perfect fit for your Duramax towing needs.
