300zx Z32 350z Z33 370z Z34 Nismo Pilot Bushing, Needle Bearing for Manual Transmissions MT

The original pilot bushing is just a metal sleeve that the transmission input shaft slides into. These sleeves usually get worn out, and leave shavings inside the bell housing. The Nismo Needle Bearing rotates with the transmission input shaft, and won't cause any wear on either the bearing or shaft.
