Victory Product Design's BMW underdrive
pulleys are engineered and designed
by their own in-house mechanical engineers
and are made using the most technologically
advanced CNC machines.
They test the designs on their own
test vehicles logging many daily driven
miles under some of the most extreme
temperatures in the United States
(Houston Texas Summers). Rest assured
that with Victory Product Design's
pulley kit, there are NO concerns
over high water temperatures or low
battery life due to extreme underdriving
of the BMW accessories.
Victory Product Design's precision
pulleys are made from 6061 T6 Billet
Aluminum and feature their own proprietary
hard anodized coating for long
life. This coating ads a true thin
surface of protective coating to
the underdrive pulleys, which are
Jet-Black, and aides in preventing
corrosion and maintaining a clean
Lightening Holes are added to reduce
the weight of the pulleys and lower
their rotational inertia, which
allows the pulleys to be accelerated
