At Specmo, we do
complete speedometer and
instrumen-tation repair on
most makes of foreign and
domestic vehicles including
certified speedometer "Speed
Check" accuracy tests.
All factory specifications will
be met, and your odometer
will be accurately set when
calibrating your instrumen-tation.
If Specmo does a conversion(mph to km/h) for
a GM vehicle, we will upload that information
to the GM VIS system so your factory warranty
is not voided.
If you have questions on any of our
calibration services, please
call our
National Toll Free
Hotline at
(800) 545-7910.
