Great OEM replacement for my C7 Corvette.

Genuine GM alternator for my C7 Corvette Stingray. Shipped in the tape sealed GM box too. Phenomenal value. Dropped right in so it fit perfectly. I see where it is looking for "ease of installation" but if you know you know...you have to remove the entire airbox and intake system to get this thing out of the engine bay so it may be "easy" but it's time consuming. BUT...easy so you don't have to take it to the dealer or a shop to replace.

Perfect!

I had the voltage regulator fail on my Z06, outputting up to 16.5 volts. This GM replacement is half what the dealer is charging and working great so far!!

Worked great for my C7 Corvette

OEM product worked great to replace my overcharging alternator. Re-used existing bolts and it looked exactly the same.
