Ordering and Compatibility

This is a universal performance head unit, not a complete vehicle kit. Verify rotation, mounting pattern, pulley style and offset, volute clocking, inlet and outlet sizes, impeller-speed calculation, target horsepower, drive capacity and bracket clearance before ordering. Contact SMG Speed with your existing ProCharger serial number and system part number when replacing or upgrading a current unit.
