Built To Transform Your L5P Without Changing Its Character

If you are looking to wake up your L5P Duramax without giving up factory drivability, the Fleece Cheetah turbocharger delivers exactly that balance. This turbo is designed to bolt in like stock, yet it completely changes how the truck feels once you lean into the throttle. Throttle response is noticeably sharper, making the truck feel lighter on its feet around town while still pulling hard on the highway. Additionally, the signature Cheetah sound adds just the right amount of attitude without becoming overbearing on long drives. What really sets it apart is how seamlessly it works with the factory exhaust brake, towing manners, and daily driving habits you already trust. You get a serious jump in power potential while keeping the truck comfortable, predictable, and enjoyable in real world use. For many owners, this is the turbo that finally makes the L5P feel like it should have from the factory.
