Had a gen 3 Eaton m90 for 2005 Monte Carlo. $258 for full rebuild kit, overpriced, should have done my research. Didn’t come with instruction. Oil container had been opened before shipping and spilled in bag. They called me for confirmation and still sent me the WRONG SIZE screw bearings, and no assembly grease for the reinstallation of the screw bearings.

Spoke with Tony yesterday.He gave me FREE advice on how to diagnose my Super Charger. I found out it was really the Alternator! Thank-you Tony!!! My hat is off to you!

SCOL is the best around and the customer service is great. I have built several projects and SCOL has always come through and delivered the best products and service. I would highly recommend them to anyone looking for a super charger or just more horse power!!!
