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 LT models, included with the available Trailering equipment.
On LT models, included with the Texas Edition or Custom Sport Truck Package.
