The
1970's, '80's and '90's
In
the mid-1970's, Gleasman started his own company
called Dual Drive Differentials (Triple-D) manufacturing
differentials for high performance racing vehicles
and passenger cars. This differential came to
be known as the Torsen® differential. It was
introduced to Toyota Racing Development (TRD)
and was incorporated into the drive line of the
Hummer.
In
the early 1980's, Vernon sold his patents for
the differential to Gleason Works in Rochester,
New York. The patent rights were later resold
to Zexel Corporation.
In
1983, Vernon received the prestigious SAE Louis
Schwitzer Award at the Indianapolis 500 for the
Torsen® differential, the most innovative
product in racing.
