Full-Width Underseat Lockbox for Chevy & GMC Trucks (2007–2019)

Keep your gear secure and out of sight with the Tuffy Underseat Lockbox, designed for the 2007–2018 Chevy/GMC Crew Cab 1500 and 2007–2019 2500HD/3500HD. With a full-width, formfitting design, it delivers over 3,500 cubic inches of lockable storage, perfect for firearms, tools, laptops, and other valuables.

Constructed from high-security welded steel, this lockbox is built tough—just like your Silverado or Sierra. Tuffy’s exclusive Pry-Guard® locking system with a 10-tumbler double-bitted key provides industry-leading protection, while weather-resistant seals guard against dust and moisture. The low-profile design mounts discreetly under the rear seat, keeping valuables hidden from view.

Access is simple—flip up one or both rear seats to open the dual lids. When extra floor space is needed, the innovative mounting system allows the lockbox to be removed in seconds from inside when unlocked, with no tools required. Chamfered corners improve passenger comfort, making this lockbox as convenient as it is secure.
