This is a replacement nose drive assembly for the Magnuson/TRD supercharger. It will replace a worn out nose drive on the Magnuson or TRD Supercharger Newer BLACK version for the 3.4L Toyota supercharger kit.
It comes with a new nose drive that is assembled ready to install with bearings, seals, slip on style pulley, coupler, sealant, Eaton supercharger oil, and new fill plug.
If your nose drive has worn bearings, a bad input shaft seal or a bad coupler you can use this ready to install nose drive to freshen your Magnuson supercharger.
NOTE- This replacement nose drive will not fit the recently released TVS version of the supercharger.
