Description
Impeller nut with counter-clockwise thread. This nut is an upgrade over stock as it has a narrow diameter. This is an advantage with upgraded impellers that have a narrow bore.
This is not a locking style nut, so it will require blue locktite on installation. Failure to properly secure can lead to a catastrophic supercharger failure.
