Calibrated Power 04.5-07 Dodge Ram 5.9L Cummins Calibrated Power HE351CW Stealth STR Turbo

The 3rd Gen Stealth STR is an upgraded, stock replacement turbo for 2004.5-2007, 5.9L Cummins. A custom designed 60mm billet compressor wheel with machine-matched compressor cover bumps the efficiency of this turbo up from 60lbs/min stock to 66lbs/min. Resulting in a 10% increase in air output over stock. The STR is designed to be a direct bolt-on upgrade and requires nothing more than removing the stock charger and dropping this one in its place.

The Stealth STR for 3rd Gen Cummins is the perfect option for those looking to replace their stock turbo with something that offers better performance, improved efficiency, and superior durability. On top of that the 3rd Gen STR is one of the quickest spooling turbos we have tested on the 5.9L Cummins. Most Cummins enthusiasts have a hard time telling the difference between a stock HE351's spool up and the Stealth STR's under light throttle, daily driving. If you daily drive your Cummins, consider the quick spool-up and added durability of the STR's compressor wheel a "must-have".
