Will this box fit my truck bed without modification?

The 69-inch width is designed for standard full-size truck beds. Measure your bed width before ordering to confirm fitment — some crew cabs run narrower at the rails.

What mounting hardware comes with this?

The box unit and lock are included. Mounting hardware and installation method are not specified — you'll need to verify how it attaches to your specific truck before finalizing purchase.

Does aluminum need any prep or coating before I install it?

Aluminum resists corrosion naturally, but inspect it for any shipping damage or debris before mounting. A quick wash and dry is standard practice before installation.
