Review & Install Video

Protects Your Stuff. If you use your F-150 for work, you need a secure place to keep your stuff, meaning tools and equipment. While you depend on your truck bed for carrying cargo, it doesn’t offer much in the way of protection from prying eyes that are eyeing up your tools. The stealthy under seat design of the Tuffy Under Rear Seat Lockbox keeps your tools and equipment out of side and safe and locked up under your rear seat.

Lots of Space. With this Tuffy lockbox you get over 4,500 cubic inches of secured storage space. It runs the full length of your rear seat and measures 56”x13”x8” (Front) tapering to 6” (Back).

Sturdy Welded Construction. This 16-gauge welded steel box features Tuffy’s Pry-Guard locking system with 1/8” thick welded steel components. A fusion-bonded epoxy powder coat protects the box from corrosion. The locks are extremely secure with 10 tumblers and are double-bitted with built-in weather seals. The box’s weather resistant lid features Tuffy’s pin-lock hinge system for added security. Chamfered corners allow for easier access for rear seat passengers.

Easy to Install. You can install your new Tuffy Under Rear Seat Lockbox with common hand tools. There is no drilling needed for installation and the box comes with mounting brackets. You will use existing OEM hardware for fastening the box. Like all Tuffy products, this lockbox is covered by their limited lifetime warranty.

Tech Note. This Tuffy Under Rear Seat will not fit in trucks that are equipped with the Sony subwoofer option.

Application. The Tuffy Under Rear Seat Lockbox is designed to fit 2015-2019 Ford F-150 SuperCrew and SuperCab models.

I just installed WeatherTech DigitalFit FloorLiners (47697-1-2) which included the rear floorboards. Will this lockbox still fit under the seat with the floorliners installed? Thanks

  • Yes, this product will fit even with floor liners installed in your truck.

I know this cargo box is supposed to fit my 2017 F-150 Lariat supercab but I'm having trouble visualizing how this will fit with the inverter that is located under the passenger side rear seat. So, will it fit with the inverter there? Thanks.

    Good box overall

    Product was as expected. I had initially an issue with my order and i got the first lockbox without a key to open it and locked. After the return everything was fine. it's really sturdy, nothing that could be broken in a smash and grab. Install was really easy. It looks good and almost like something stock. As general advise i wound't put anything too valuable inside for extended period of time without surveliance or if you are in a high crime area. The lockbox could be easily stolen by 2 people by removing both seat bolts. All they need is a socket and wrench. Would have been better to find a way to bolt it from the inside to the floor without access to the bolts from the outside.

    Tuffy Lockbox

    This is the second Tuffy product I've purchased. As with the first this box is not surprisingly very well constructed and fits perfect. I was able to fit all the tools and supplies that were in my older box in this one.

    Perfect fit and look

    This is my first truck and I was lamenting the lack of a locked trunk, but with the install of this box, it's all good! This goes in and out fairly easily and I was able to install this by myself. Most importantly, it looks like part of the truck and not an addition!

    Practical and heavy duty!

    The fit under the rear seat is perfect. Box was torn on delivery, but there was no damage to product. Very easy to install. Very secure, I am confident securing my firearms and valuables in the lock box. Once main brackets are bolted to floor, box can be removed without tools with internal bolts. Bought husky floor mats for my truck after installation, had to remove box to fit mat under box.
