Fitted and certified in Miami

We fit and certify it on site

We fit Tough Dog GVM upgrades at our Miami workshop and complete the certification on site, so you drive away with the paperwork done.

An approved GVM kit has to be fitted complete, under its own kit part number, to be certified. We fit every part in the approved kit for your exact vehicle, and nothing is swapped or left out.
