Diamond T Torque Converter, Dodge (2003-07) 5.9L Cummins, 550hp Single Disk, Low Stall

These Torque Converters are built in the USA with the highest grade components and come with a Lifetime Non-Transferable Warranty for defects in material and workmanship under normal and proper use. They are designed to improve acceleration, pulling power, and efficiency of your vehicle to the max. Unlike other "mass produced" re-manufactured torque converters, Diamond T technicians keep all of the original parts together during the re-manufacturing process to assure a matched set of components. Other re-manufacturers disassemble hundreds of torque converters and mix all of the parts in large bins. Keeping the parts together results in improved quality. All parts are inspected thoroughly and any marginal parts are replaced. They take the TIME to build quality into each and every Torque Converter. Many other companies do not measure the thickness of the housing and when they machine the surface it makes the metal too thin and leads to early failure. If your housing is less than the OEM specs, they replace it with a new one. The torque converters are precision balanced with a computerized balancer. Only the best clutch materials are used. The torque converters are pre-charged with transmission fluid. This helps to prevent rust on the internal components leading to early failure in case it is exposed to any humidity before installation. Quality testing is performed on each and every Torque Converter before it leaves the facility.

With this new up grade you can totally tell the difference! No more slop in shifting. And I am more confident about pulling heavier loads. Great customer service. Would buy from again. Thanx
