2010 Chevrolet Silverado 1500 Alternators

Genuine GM alternators for the 2010 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.

How you know

A battery light, dimming headlights at idle, or a no-start after a short drive. On a light duty pickup, cab configuration, drivetrain and box length all split this group, so the badge on the tailgate is not enough to order from.

Why order factory

• We catch the wrong part before you do. VIN verification is free on every alternators order.
• Fast out the door. In stock alternators ship within hours, not days, from Dallas.
• No hassle returns. If the alternators is not right, send it back.
• Warranty intact. OEM alternators keep coverage that an aftermarket part can void.
• Wholesale pricing. Most alternators numbers land well below dealer list.

Confirming fitment

Materials and coatings are specified, not approximated, which is why factory parts last through more heat cycles. Check the VIN before ordering anything that has to bolt to something else. Shipping is calculated on real weight and distance, which usually beats a padded flat rate.
