GMC Sierra 1500 Tool Box FAQs

What size crossover tool box fits a GMC Sierra 1500?

Crossover box length matches bed width. As a full-size pickup, the Sierra 1500 typically takes a crossover box around 69 to 72 inches. Check each box's listed dimensions against your bed rails, or rely on the vehicle filter on this page.

Does bed length matter for a Sierra 1500 tool box?

Not for crossover boxes, which are sized to bed width. Bed length matters for side mount and top mount boxes, which run along the bed rail, so check the listed length against your bed.

What type of tool box is best for a Sierra 1500?

A crossover box gives the most lockable storage behind the cab. Side mount or top mount boxes keep the center of the bed open for long material, and a tool chest sits on the bed floor so the rails stay clear.
