Supercharger Warranties

We stand behind everything that comes out of our shop. Based on decades of experience, exceptional engineering, and rigorous testing standards on any product that bears the Mallett name, you can have a high degree of confidence that what you buy will do what we say it will.

That said, as with any purchase – and especially any purchase in the vehicle after-market space – there is a certain degree of risk when it comes to making any modification to your automobile. Choose your installer and your service shop carefully.
