Smeding EZ Drop-In Turbo | 2003–2007 5.9L Cummins | Direct HE351CW Replacement

The Smeding EZ Drop-In Turbo is a direct bolt-in upgrade for 2003–2007 Dodge/Ram 2500 & 3500 trucks with the 5.9L Cummins. Built as a true replacement for the stock Holset HE351CW turbo, it installs using your factory manifold, oil lines, and intercooler piping—no modifications required.
