Underseat Storage Box 99-07 GM Extended Cab

The HUSKY LINERS Underseat Storage Box for 99-07 GM Extended Cab trucks is a purpose-built storage solution that maximizes usable cargo space in the tight footprint beneath extended cab seating. This black textured plastic gearbox taps into wasted dead space that typically goes unused, providing secure storage for tools, recovery gear, camping equipment, or other essentials without sacrificing interior comfort or convenience.

Measuring 61 inches long by 16.5 inches wide and 10 inches deep, this underseat storage box leverages the full length of the extended cab platform while maintaining low-profile installation that doesn't interfere with seat operation or headroom. The textured black plastic construction resists impact damage and UV degradation common in open-bed truck environments, while the compact footprint ensures passenger access isn't compromised. The 11.15-pound weight keeps installation manageable without requiring specialized equipment or reinforcement.

This storage solution is engineered specifically for 1999-2007 GM full-size trucks with extended cabs—the platform that sits between standard regular cabs and crew cabs, offering a balance of seating and bed length. Contractors, off-road enthusiasts, outdoor recreationalists, and anyone running gear-heavy operations benefit from having organized, weatherproof storage that keeps equipment accessible but out of sight. Rather than relying on bed-mounted toolboxes or cargo nets that consume bed space, underseat storage preserves truck bed capacity while keeping smaller high-value items secure and protected from the elements.

HUSKY LINERS is known for manufacturing protective interior and exterior truck accessories engineered to OEM specifications. This underseat gearbox fits the brand's focus on maximizing truck utility without requiring permanent modifications or aftermarket fabrication. For GM extended cab owners seeking additional storage without compromising functionality or aesthetics, this is a direct-fit option that integrates seamlessly into the factory truck interior.
