This all aluminum storage box gives you the most space available. TIG welded and finished in a black powder coating makes this box strong and durable. It features one single compartment measuring 45 1/2" long by 10" wide by 3 5/8" deep. It has two separate lids to allow access from both seats and has separate locks with matching keys. We have redesigned and reengineered the seat rails to allow clearance for the box without having to use spacers between the seat rails and the seat frame. This keeps the rear seat in the factory location without the need to raise the seat. This is the most usefull modification that can be done to the 3rd generation Tundra CrewMax.
