Features
- Uses wheel-well space: The box sits over the rear wheel well and puts that awkward space to work, leaving the open bed floor for cargo.
- Side-specific fit: Each box is shaped for one side of the bed, so you can run one alone or pair it with its opposite-side twin.
- Gloss black diamond plate: Gloss black ARMOR TUF covers the aluminum diamond plate, a light metal that will not rust.
- EXTREME PROTECTION lock: A tamper-resistant lock retracts flush when locked, and two keys come with the box.
- Full weather seal: A seal around the lid keeps rain, dust and grit away from your tools.
- Works with some caps: Weather Guard says the low body suits some truck bed caps, so check your cap's inside clearance first.
Description & Fitment
For the passenger side, the 173-5-01 Pork Chop puts 3.4 ft³ of gloss black aluminum storage over the wheel well. Its 46.75" x 13.5" x 19.5" body is the earlier -01 shape, with two keys for the EXTREME PROTECTION lock.

Frequently Asked Questions
Will it fit my Silverado 1500?
It is on our fitment list for that truck. Wheel wells differ by bed, so measure the space over yours before ordering.
Can I put it on the driver side?
No. It is built for the passenger side. The 172-5-01 is the matching box for the other side.
Do I have to drill my truck?
Yes. Weather Guard's Pork Chop manual mounts the box with blind fasteners in drilled holes. Check under the vehicle first, and near the fuel tank install the floor bolts from below in 3/8" holes instead of using blind fasteners.
How does the -01 differ from the -04?
The -01 is the classic Pork Chop shape with the EXTREME PROTECTION lock, at 46.75" x 13.5" x 19.5". The current -04 wheel-well box is 46.63" x 15.43" x 16.4" and uses the 1Key UltraLock.
Will it work under a bed cap?
Weather Guard says the low body works with some caps. Measure the clearance inside your cap against the box's 19.5" height before ordering.
What about an aluminum truck bed?
Weather Guard's manual calls for zinc-rich primer on every drilled hole and plastic washers around each blind fastener in an aluminum bed.
Installation
Here's the short version. Follow Weather Guard's install sheet (below) for the exact positions and hardware.
- Set the box in place with the cover open, flat on the floor and about 1" from the bed rail; check the tailgate closes. Fasten to the bed floor, not a liner or mat.
- Hold the end mounting angle against the box with its foot on the stake pocket or inner wall, mark and center punch one hole on each.
- Drill both 3/16", open the box hole to 3/8" and the stake-pocket hole to 1/2", set the blind fastener and bolt on the angle.
- Fit the floor mounting angle (spacer if needed) or the lower mounting angle as shown.
- If the box can rest on the wheel well, drill 3/16" then 3/8" through box bottom and wheel well top and bolt through instead.
- Check each hole is deep enough before setting a blind fastener; on aluminum beds follow the upfit steps on p2.
