2021–2023 Silverado 1500 & 2500 HD 3500 HD BCM 13531840 — Programmed to Your VIN

GM Body Control Module 13531840 — Programmed to Your VIN

We program GM Body Control Modules to your vehicle's exact VIN and factory RPO codes using OEM GM calibration data. VIN programming, option configuration and module setup are done before it ships — no dealer visit.

We can also add features your vehicle didn't come with — cruise control, fog lights, or auto-lock enable/disable, where the hardware supports it. Included in the price.

• Chevrolet Silverado 1500 2021
