2020 Silverado 2500 Engine Options In Stock

Why Buy a 2020 Chevy Silverado 2500 Engine from Auto Power Source
Every 2020 Silverado 2500 engine we list is inventory-verified against its donor vehicle, cataloged by VIN, and stored securely until it ships to you. Our certified technicians visually inspect every unit before it is cleared for sale; we do not run compression or leak-down tests.
Both 2020 Silverado 2500 engines we stock are 6.6L, so displacement alone will not tell you which one you need — the diesel (opt L5P, VIN Y) and the gasoline (opt L8T, VIN 7) are entirely different engines that happen to share a number. The 8th VIN digit and the option code are what separate them. Text your VIN and we will confirm the exact match before you order.

2020 Silverado 2500 Engine Buying Guide
-
Confirm the 8th-digit VIN code. The 2020 Silverado 2500 diesel ships under VIN Y and the gasoline under VIN 7 — with both engines at 6.6L, the 8th digit is what separates them.
-
Match the engine option code. Our diesel unit is opt L5P and our gasoline unit is opt L8T; the option code is cataloged on every listing.
-
Do not order on displacement alone. Both units read 6.6L. Diesel and gasoline share nothing that matters here — fuel type is the fitment, so confirm it before you order.
-
Check brackets and ancillaries. Accessory mounting and sensor harnesses can differ between fitments — tell us what came off the car.
-
Always run the donor VIN if available. We provide it on request for any Silverado 2500 engine in inventory to verify mileage and history.
Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
