LS billet alternator kit

Glad I came across this kit as I noticed one day while driving my r32 that my voltage was rather low. I looked into an oem replacement but then came across this kit. Everything arrived well packaged and quick shipping. I’ve yet to install this on my car as I’m still deciding which LS alternator I wanna go with and I’ll give an update soon after it’s installed.
