Each of our GM torque converters have a wide variety of stall speeds available as well as the hardware needed to install them into the transmission. These converters have the lockup option available in addition to having various high performance upgrades including brazed impeller, turbine, and fins, billet lids, anti ballooning plates and more. These will add a higher torque capacity to the unit. In turn, adding even more overall durability and longevity to the converter.
