2003-2004 Ram 5.9L Cummins Torque Converters

Your 2003-2004 Ram 2500 or 3500 5.9L Cummins can make a bunch of power with only a few mods and tow and haul heavy loads, but the stock torque converter can struggle to handle it all. Tier One's performance torque converters for 2003-2004 Ram 5.9L Cummins are built from the ground up to hold and handle a ton of horsepower and torque, as well as being able to tackle tough towing challenges without warping, cracking, or burn-up. Our Ram Cummins torque converters range from basic stock replacements to high-strength billet torque converters with multi-disc designs that can hold all the power you can squeeze out of your Ram 5.9L Cummins. We also offer torque converters with a variety of different stall speeds so that you can fine-tune your transmission's shifting for whatever application you have in mind. If your torque converter has already failed and sent debris through the rest of the system, a simple replacement might not be enough, and you may need to swap the whole unit with one of our 2003-2004 Ram 5.9L Cummins Complete Transmissions. A torque converter working hard under a heavy load generates massive amounts of heat, so keep that heat from cooking your fluid and ruining your new converter with one of our 2003-2004 Ram 5.9L Cummins Transmission Coolers. To get the most out of your new converter, your transmission needs to apply the correct fluid pressure, so ensure your lock-up is firm and reliable by upgrading to one of our 2003-2004 Ram 5.9L Cummins Valve Bodies. While you have the transmission disconnected to install the converter, it's the perfect time to upgrade other weak points like the flexplate or input shaft, so see what else you should swap in our 2003-2004 Ram 5.9L Cummins Transmission Parts.
