Nachi Supercharger Pulley Bearing KR22W8 – For Mercedes SL55 AMG, E55, S55, CL55, CLS55, G55

Whining noise from the supercharger?

That’s the pulley bearing singing its death song.

This Nachi KR22W8 is the correct replacement for Mercedes 5.5L Kompressor cars—SL55, E55, S55, CL55, CLS55, G55.

2003-2011 models.

Nachi is OEM-grade Japanese bearings, way better than mystery metal.

12-month warranty included.

If your supercharger pulley has play or sounds like a jet spooling down, swap this in before it grenades.

Read the listing notes—this is the bearing only, not the whole pulley.
