Standard on all Tundras, Auto LSD works like a traditional limited-slip differential—with a high-tech twist. Instead of controlling slip mechanically, Auto LSD applies brakes individually to wheels with no traction. And unlike Traction Control, it doesn't cut engine power. This helps give you control and distributes power where it’s most effective. Best of all, because the system utilizes the brake system, there are no extra components that add to overall ownership costs.
