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 2004.5-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 Variable Vane
Brake (VVB) 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.

VVB 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 VVB 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 Variable
Vane Exhaust Brake is also firmware updateable via the internet using
your computer's USB connection and is the perfect fit for your Duramax
