Description:

The Original KC38r is back and better than ever! We have spent several years of R&D modifying and battle testing our original ball bearings, so that would could bring you the best and most reliable ball bearing design KC Turbos has ever produced. The 66mm compressor wheel is drastically different, It is a larger, 7x7 wheel and is modeled after the KC300x Gen 2 compressor wheel. The Turbine Wheel takes design notes from the 366sxe. This Turbine wheel is not only bigger, but stronger. It has thicker blades, thicker hub, and thicker backing, this makes it much less prone to fatigue and wheel burst. The turbine wheel is also much larger at 73mm vs the old 70mm with an increased shaft thickness from a 6.4mm to 7.5mm. 

**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.**

**Our turbos are designed to fit directly in 7.3 equipped pick-up trucks. Although our turbos can drop into 7.3 equipped Vans, you will need to modify the turbo intake boot and down-pipe for proper fitment**
