Description

This is the DuraMax Tuner Stealth 67G2 Turbo, designed for the 2001-2004 Chevy/GMC LB7 Duramax. It's engineered to be safe for towing, enjoyable for daily driving, and competitive in performance. It features a custom 67.7mm compressor milled from high-strength 7075 Aluminum with a TCT design to maximize peak power. It includes a unique, OEM-appearing, anti-surge ring sleeved into the factory IHI compressor cover. The center section is liquid-cooled with a 360-degree thrust bearing for reliability. The turbine side boasts a larger turbine than factory, reducing drive pressure and lowering EGTs, allowing for nearly a 1:1 drive to boost ratio.
