High-Security Lockbox for the '07-2018 Chevy Silverado and GMC Sierra Crew Cab Pickups

Tuffy's Model 340 offers 2,100 cubic inches of storage and fits under the driver's side and middle rear seats of the pickup, leaving some space available under the rear passenger side seat. Items 35 inches and shorter fit into the box with ease. Each lockbox is comprised of powder-coated 16-gauge welded steel and features chamfered corners to allow easier passenger access and a more concealed form. Model 340 lockboxes can also be customized by users with optional foam lining inserts.

The company's patented Pry-Guard locking technology protects the contents of the box from would-be thieves. Its 10-tumbler double-bitted locks can be opened from either side of the vehicle.

Tuffy's Model 340 is installed without drilling by fastening to the original equipment seat bolts using the included mounting system comprised of two 16-gauge steel brackets which affix to the back of the box and extend to the rear of the vehicle under the seat. The innovative mounting system developed by Tuffy Security Products allows users to remove the box from the vehicle from inside the box itself when unlocked by using the wing knob nuts.
