Most Popular Questions

Is this a quality drop in replacement for my 2003 6.6L GMC?

Will I notice a power gain and fuel millage gain?

View Staff Answer 

The Fleece LB7 Cheetah Turbocharger is a great drop in replacement for the Duramax owner who’s looking to build more power out of their LB7. You’ll defiantly see a nice HP and MPG difference running turbocharger, but gains will vary depending on the supporting modifications.
