Making the truck more useful for upfitters out of the factory, the 2025 Chevy Silverado will offer the Universal Vehicle Module (UVM) – previously available only on GM police vehicles – as an extra-charge option for the model year.
The Universal Vehicle Module (RPO code KGU) is now available to order on the 2025 Chevy Silverado 1500 for the Work Truck (WT) trim level only, and on the 2025 Chevy Silverado HD on all trims. It also became available late in the 2024 Silverado model year.
The UVM includes software that provides vehicle data over the open CAN network, using SAE J1939 protocols. CAN is the Controller Area Network, technology that enables communication using SAE J1939 for commercial vehicles and similar applications. The module includes ten switchable inputs/outputs and a Custom Configuration Tool to integrate upfit equipment controls for everything from individual users to fleets.
The 2025 Chevrolet Silverado offers software features that support Auto Vehicle Start, Shutdown Inhibit, Fast Idle and Snow Plow. Auto Vehicle Start can be used for indirect alternator control to maintain battery voltage at the correct level, or for indirect temperature control in the interior.
Shutdown Inhibit is useful for keeping a utility truck running to power various equipment, while Fast Idle boosts power output for that equipment, among other uses. Snow Plow Support disables active safety features that are incompatible with snowplow use.
The Universal Vehicle Module is available on the 2025 model year of the Chevy Silverado 1500 and Chevy Silverado HD at a cost of $295 extra. The package includes the module, a customer interface harness and instructions. It is also available on the Chevy Blazer EV PPV and the GMC Sierra.
As a reminder, the 2025 Silverado 1500 has four powerplant options, including  the new-for-2024 3.0L I6 LZ0 turbodiesel Duramax engine rated at 305 horsepower and 495 pound-feet of torque, the newly TurboMax-branded turbocharged 2.7L I4 L3B gasoline engine cranking out 310 horsepower and 430 pound-feet of torque, the atmospheric 5.3L V8 L84 gasoline engine developing 355 horsepower and 383 pound-feet of torque, and the naturally aspirated 6.2L V8 L87 gasoline engine providing 420 horsepower and 460 pound-feet of torque. .
The 2025 Silverado HD, meanwhile, equips the naturally aspirated 6.6L V8 L8T gasoline engine, rated at 401 horsepower and 464 pound-feet of torque as standard, with the 6.6L L5P engine, rated at 470 horsepower and 975 pound-feet of torque as an option.
The GM T1 platform underpins both truck variants, with a more capable variant used for the Chevy Silverado HD. Production of the 1500 will take place at the GM Fort Wayne plant in Indiana, the GM Oshawa plant in Canada, and the GM Silao plant in Mexico, while the HD is produced at Oshawa and the GM Flint plant in Michigan.

not something most people care about. This is a fleet thing.
Or off roader thing. It can be useful for the guy that just wants to set up his truck for more utility as well. I would say half the buyers might have some interest. Shoot, even guys that tow would like to add some useful electrical accessories much easier.
