If your supercharged Mercedes AMG is making a whining or grinding noise from the front of the engine, the supercharger pulley bearing might be shot.

This is a brand new Nachi bearing, part number KR22W8.
It fits a whole bunch of AMG monsters from the 2000s: SL55, E55, S55, CL55, CLS55, and G55.
It's the exact bearing that rides on the supercharger pulley.

This is a common wear item.

Grab this Nachi bearing (which is great quality), and if you're handy, you can press out the old one and press this in.

Comes with a 12-month warranty.

Quiet that supercharger down.
