Perfect for towing, drag racing, daily driving and everything in-between, the TapShifter installs in no time and provides factorylike operation, functionality and styling.
INSTALLATION:
The TapShifter installs using OEM high quality connectors for a completely plug and play installation in less than 30 minutes.
