Quality-Built® 8116607N OE Replacement Alternator, New
Jul 25, 2019
Nice 100A Alternator for '95 Tahoe.
Have to install a new alternator after the old one failed on me. Install this one, no more problems. Be sure your grounds and battery are in good condition.

The alternator part is now installed in my Chevy. My mechanic friend was able to install the part, without any trouble. The unit is working well, as shown on my new internal gauges. I did have to pay a substantial shipping cost. However, the delivery time was pretty good, & the overall cost ended up less, than if i bought the unit locally.
