The stock converter on your 2017-2019 GM 6.6L Duramax L5P can withstand basic everyday applications; however, it's cant handle the elevated levels of horsepower and torque that comes with various performance modifications. If you're gong to throw down huge amounts of power in your GM 6.6L Sierra/Silverado 2500/3500, it's best to replace the factory converter with one of the premium aftermarket torque converters we offer here at Alligator Performance! These upgrades are capable of handling much higher levels of both horsepower and torque, giving your GM Truck consistent transmission performance and functionality in every situation.
