Matrix ST Truck Topper

Secure your gear. Skip the compromise.

The Matrix ST was built for truck owners who want secure, weather-protected storage without sacrificing accessibility or modern utility.

With its windowless design and Black River’s patent-pending opening system, the Matrix ST keeps valuable gear out of sight while giving you full, unrestricted access to your truck bed.

No crawling.
No digging.
No climbing halfway into your bed just to reach your tools or equipment.

Because your truck should work with you — not against you.


Built for Work. Ready for Anything.

From tools and recovery gear to hunting setups and camping equipment, the Matrix ST is designed to keep your gear protected, organized, and secure wherever the road takes you.

Its clean, windowless design adds privacy and peace of mind while giving your truck a more aggressive, modern look.

Perfect for:

  • Work trucks
  • Contractors
  • Outdoor gear
  • Hunting equipment
  • Overland setups
  • Recovery gear
  • Everyday truck use

Pair it with the Matrix Lighting Kit for improved visibility when loading gear at night or before the sun comes up.


Full Bed Access Changes Everything.

Traditional toppers force you to crawl into your truck bed to reach gear buried in the front.

The Matrix ST changes that.

Its patent-pending opening system provides wide-open access to your truck bed, making it easier to:

  • Reach tools and equipment
  • Organize gear
  • Load larger items
  • Access the front of the bed
  • Maximize usable storage space

Once you experience unrestricted bed access, it’s hard to go back.


Secure Storage Without the Hassle.

The Matrix ST features a dual adjustable slam-latch system with a single-point rear release designed to help protect your gear from theft, weather, dust, and debris.

No exposed handles.
No dangling locks.
No unnecessary complications.

Just clean, secure functionality built for real truck use.


Built to Handle Real Life.

Constructed from heavy-duty .063 automotive-grade aluminum with a durable matte black powder-coated finish, the Matrix ST is engineered to handle rough roads, changing weather, and everyday abuse.

Features include:

  • Double-walled aluminum construction
  • Premium perimeter weather seal
  • OEM-quality gas struts
  • 15" low-profile LED brake light
  • No-drill installation
  • Fits in standard 7-foot garage openings

Want even more convenience? Add the Matrix Power Lift Kit for push-button opening and closing.


Modern Utility. Aggressive Style.

The Matrix ST combines rugged utility with a clean, modern profile that looks right at home on today’s trucks.

No oversized bulk.
No outdated fiberglass look.
No compromise between function and appearance.

Just secure storage, unrestricted access, and modern truck utility built the Black River way.


Don’t Compromise. Demand More.

The Matrix ST helps you carry more, secure more, and access more — whether you’re headed to the jobsite, the trailhead, or somewhere in between.

Does the job, economical and a perfect fit
Size: 1" x 1" x 1"
Bought exactly 1 year ago for 3rd Gen Tundra. So far, it really does the job. At first I didn’t realize how awesome it was until I had to remove and clean it yesterday. Although I keep my truck immaculate inside and out, after 1 years use, the filter had become extremely filthy and the air had an old mildew, vomit, stank smell. When clean and set for fresh air, I can only faintly notice diesel exhaust smells from those in front of me. I also notice little to no dust accumulation on my dash and flat surfaces. In my opinion the K&N cabin filter kit is an essential tool for cleaning this filter. K&N made the filter, so I would imagine that they know how to clean and refresh it properly. By the way, refresh solution is nearly fragrance free. I bought the refresh kit at a big box auto supply and it came in a mostly black box instead of the white box as sold on here. Don’t know if that means the formulation has changed or not.

Great quality and performance
Size: 1" x 1" x 1"
The quality of the filter is great and it is easy to installed in your car. Also, it helps to improve the performance of your vehicle, keep clean air flowing and avoid bad smells. What I love about it it’s the option to washed it and reuse it over an over.

Awesome product!
Size: 1" x 1" x 1"
Awesome product! Fit just as it should. A lot better then buying the replacement ones every time I do an oil change. I drive a mile of gravel roads everyday and this helps keep the dust from coming into the vehicle.
