2013 Chevrolet Silverado 1500 Alternators

Genuine GM alternators for the 2013 Chevrolet Silverado 1500, at wholesale prices. Alternator output rating varies by electrical load, so a truck with a tow package or upfit wiring takes a different unit. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019.

Symptoms to look for

A battery light, dimming headlights at idle, or a no-start after a short drive. On a light duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.
