Product Details

Extang Trifecta Toolbox 2.0 93455


    The Trifecta Toolbox 2.0 tonneau cover works with most 18-20" toolboxes. This allows full access to the toolbox while keeping the cargo in your truck bed protected.
    Extang's triple fin seals do a great job of protecting the truck bed from rain and debris. They exceed OEM standards and can be replaced if damaged
    The patented L-Channel bracket uses a weather-tight seal to bond the tonneau cover to the toolbox. This fills the gap to create a solid fit to keep the elements out.
    The Trifecta Toolbox 2.0 uses an aluminum frame and support bars along with premium grade, leather grained vinyl. The MaxHinges feature a double pivot design for extreme durability and sealing.
    Re-Engineered, the EZ-Lock Clamps now require less physical effort to open, and they self-lock when clamped down to the bed flange.
    Our new cab clamps lead the industry by attaching directly to your bed flanges without damage or alteration to your bed caps.


The Extang Trifecta 2.0 Tri-Fold Tonneau Cover is a high-quality truck bed cover with a tri-fold design that provides ease of use, stylish appearance, and long-lasting durability. It is compatible with full-size trucks with bed lengths of 6 ½' and 8' and can accommodate most standard 18-20" toolboxes.

The Extang Trifecta 2.0 Tri-Fold Tonneau Cover is user-friendly and requires no assembly or drilling for installation. Simply position the cover on your truck, tighten the clamps, and it is ready to use.

Price Guarantee

Lowest Price Guarantee

We work hard to ensure that the prices of our aftermarket truck bumpers are the best available online. That’s why we guarantee that you’ll get the lowest price on all of our bumpers and accessories. Here’s how it works:

  • We guarantee that the price of our aftermarket truck bumpers is the best available online. If you find an online store that offers a specific model at a lower price, let us know and we’ll match their price for your purchase.
  • If you find that the exact bumper at an even lower price online within 6 months after your purchase, we will refund you the difference. Simply send a price difference refund request to support@bumperonly.com. This applies even to the prices from our own store at BumperOnly.com
  • The competitor must be an online retailer with no physical stores and they must be an authorized dealer of the bumpers or accessories in question. The competing online store must also have the product in stock on their website for our price match guarantee to apply.
  • The price match guarantee does not apply to online marketplaces such as Amazon, eBay, Overstock or any other similar websites. The competitor must be selling the item directly on their own online store.
  • Additional promos cannot be applied in addition to the price match guarantee. For example, the free gift promo cannot be added on top of the price match guarantee. Only one promotion can be applied per purchase.

Once we confirm that your order is eligible for our price match guarantee, you can be confident that you’re getting the very best deal online.

Whether you’re looking for heavy-duty truck bumpers by Ranch Hand, a winch bumper by Fab Fours, or any other aftermarket truck bumper, if you shop with BumperOnly, you’ll never have to worry about buyer’s remorse.

For any questions about our price match guarantee, feel free to get in touch.

Shop without fear. Let BumperOnly take care of the rest.
