Say goodbye to leaking, worn-out transmission cooler lines with the Power Driven Diesel 48RE Transmission Cooler Line Replacement Kit for your 2003-2007 Dodge 5.9L Cummins.

Designed to replace the fragile factory steel lines, this kit includes everything you need to upgrade to durable 1/2” ID cooler lines that maintain the stock routing from the transmission, through the heat exchanger, and to the air-to-oil cooler in front of the radiator. Built for reliability, these premium hoses are made in the USA, rated for 300°F and 300 psi, and have been tested over 100k miles on high performance Cummins tow rigs. Unlike the generic hoses you’ll find at the local auto parts store, these won’t crack or fail after a couple of years. Plus, the kit now includes an adapter for non-standard ports on aftermarket heat exchangers, making it even more versatile. With rubber-coated line clamps for a clean, secure installation, this is hands down the best transmission cooler line upgrade for your 48RE.

Don't take chances with subpar hoses, get the kit that’s been tested, proven, and built to last.
