Garrett / Turbonetics Big Shaft turbo rebuild kit is for most turbos with a 7.93mm shaft diameter where the compressor wheel sits. There are different models that have different size journal bearing so please measure your journal bearing dimensions to confirm this rebuild kit fits your turbo. The Big Shaft rebuild kit may fit some Precision big shaft turbos. If your shaft measures 6.35MM then you most likely need the Garrett TO4E turbo rebuild kit.
