KC Turbos 2003-2007 6.0L Stage Two

The KC Stage 2 64mm turbo works great on stock injectors, but to fully take advantage of all the extra air flow we recommend a 175/30 or 190/30 injector. This is a great turbo for those looking to push the limits of their truck. Built for those who are looking for more top end power but still want to have the ability to tow max weight, the Stage Two is a great drop-in upgrade. This turbo will tow max weight with ease as long as you watch your temps and keep your rpms up. This turbo has a very similar whistle to the Powermax/2003 turbos.

We highly recommend Custom SCT tuning to go with your turbo.
