*This turbocharger does not fit on California emissions-equipped trucks*

Stealth's custom-built Mach 2 (67mm) compressor wheel is specifically designed to maximize peak power while maintaining a wide, useable powerband. To fit the monster compressor wheel, they've developed a unique, OEM appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. The wastegate is even updated to make sure you have the most amount of power and the quickest spool-up.

With the all-new compressor side and center section put together, turbine wheel and exhaust housing upgrades had to be made. The LB7 Stealth Mach 2 (67) features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. This monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure. This not only helps make more power but also manages EGT's under heavy load.

Building the LB7 Stealth Mach 2 (67) meant designing a turbo that's safe to tow reasonable loads with, fun to drive every day, and a class-leading competitor. If you think street-able, clean, stealthy power is cool then this is the turbo for you! No stones left unturned when engineering the LB7 Stealth Mach 2 (67). The custom profile on the compressor wheel matched to the custom turbine wheel means you get power and drivability.
