Heavy-duty automatic locking rear differential

Silverado® offers an automatic locking rear differential for more grip and less slip when you need it most. It sends power to the rear wheel with grip if the other wheel loses traction, to help you stay in control while towing or carrying heavy loads, or when you're off-road.

On Work Truck and LS models, requires the available Trailering Package.
On LT models, requires the available Trailering Package, Max Trailering Pack or All-Star Edition.
