The stage 3 turbo is a MONSTER and will run great on the dyno and the track, with great drive ability around town. We do not recommend this turbo for those looking to tow heavy loads, that does not mean tow but this turbo is better suited for making power rather than towing heavy loads. This Turbo is NOT recommended for stock injectors. This is the Turbo for you if you want to be able to daily drive your truck during the week and race in competitions on the weekends. 

**EXHAUST BRAKES:  We get asked a lot about exhaust brakes and if they work with our turbos.  We have found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues.  These brakes typically use some sort of flapper to close which causes extreme exhaust back pressure to aide in braking.  This can be hard on a turbo and motor and is not recommended.  It will be up to the customer to verify fitment and functionality.**

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

**Polished covers can take up to 1-2 weeks lead time**

Here are a few video links to show the power potential and towing power of the turbo.

night and day difference.

Great company!, I purchased the KC stage 3 turbo for my 2007 Ford 6.0 and couldn't have been more satisfied with the fitment and performance. This was an upgrade from the old Garrett Powermax, what a night and day difference.

Customer service is amazing.

Customer service is amazing. I was having issues with my order being fulfilled within five minutes of contacting customer service my issues have been resolved. Very friendly and willing to help.

UPDATE: The turbo is amazing, from build quality to performance is amazing. I absolutely recommend buying a KC. Whether or not you’re going for high horse or just trying to wake the truck up a little bit you will be happy.

Best turbo

The turbo is literally a monster as described .
Paired with 190/75 and supporting mods on daily driven truck
Truck turned into a race car overnight . Moves 6500 effortlessly. Drive-ability is perfect with Vgt , the power is incredible . Never shy away from a race now with this under my hood. Best turbo ever paired with my setup hands down . Buying anything else for injector range listed is a waste of money .
Well done KC , you have refuelled my addiction
Bravo !!!
