They aren't unlimited drivetrain warranty though, and also they do NOT cover the labor removal nor reinstalling of the units. So even if the unit craps out they will just replace the unit / parts for free but you still foot the bill for of the labor.

Another thing is that they cover up to X amount. Like maggy covers up to 12k on engine, 2500 for transmission and 1500 for rear axle components.

And one last thing, the warranties do NOT start from the odometer you already had. It gets deducted. As in, if you have 1 year / 10k on the car already, FI warranty will have 2 years / 50k left and not 3 years / 60k miles.

Those are just the general stuff which applies to X supercharger but does not apply to Y supercharger. Each has different clauses and how it works. I suggest reading specific warranties for specific units.

Oh and 1 thing that applies to ALL. NEW UNITS ONLY, used units are NOT covered by any warranty. Basically, having at least some warranty is better than absolutely nothing however, they are no where as great as the GM warranty (EXCEPT for Callaway, it is THE only aftermarket manufacturer that minics the GM warranty 100% but you also spend 17k for their SC package instead of 10k).
