Sets into place beneath the rear seat with no drilling or hardware; typically installs in 10-15 minutes.

Product Overview

The GearBox is a full-length under-rear-seat storage container built from durable, impact-resistant material. It keeps tools, recovery gear, and everyday items secured and separated so nothing slides around the cab.

At 68.5in wide, it spans the full Extended Cab floor, turning wasted space beneath the rear seat into a clean, hidden storage solution.
