Putting a Toyota Bullett Truck Bed Cover on your truck is one of the best upgrades you can add to your rig. As it creates a more aerodynamic profile for your vehicle, the tonneau cover increases gas mileage, makes your truck look great, and protects your valuables with its Secure Auto-Latch System which secures the cover when closed by latching and locking at the same time. No secondary locks are required and the cover can't be opened without opening the tailgate.
