The KC 300103 is an S300SXE-style turbine wheel for a stock 7.3 Powerstroke turbo. It is the exhaust wheel only. The blades are larger than stock, so the wheel drives the compressor harder and spools sooner.

KC does not recommend it on a stock compressor wheel. The extra drive exaggerates surge. Pair it with a billet compressor wheel. It is component-balanced and drops into a TP38 or GTP38. It will not fit a GTP38R dual ball-bearing turbo. Housings, bearings, and the compressor wheel are not included. DIY installs are not covered by warranty. It cannot be shipped to California.
