The Diesel Performance Converter DPC D1000 Stock Stall Super Single Torque Converter gives you durability up to 500HP in your 1994-2007 Dodge 5.9L Cummins. This Torque Converter features an all new billet lock-up piston, and a billet front cover to help prevent any deflection of the lock-up surfaces. The larger lock-up friction makes this converter handle the common power upgrades made by many Cummins owners. Each torque converter is built with torrington bearings for reduced internal friction. DPC also reinforces the internal components by TIG welding or furnace brazing.
