Fits With Existing Toolbox
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.
Superior Seals
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
L-Channel Design
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.
Premium Quality
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.
EZ Lock Rear Clamps
Re-Engineered, the EZ-Lock Clamps now require less physical effort to open, and they self-lock when clamped down to the bed flange.
Jaw Grip Front Clamps
Our new cab clamps lead the industry by attaching directly to your bed flanges without damage or alteration to your bed caps.

Choosing between bed accessories can be challenging, especially when weighing the benefits of toolboxes and tonneau covers. But with the Trifecta Toolbox 2.0 from RealTruck® and Extang, you get the best of both worlds without sacrificing functionality or aesthetics.

This premium tonneau cover is specially engineered for use alongside crossover-style toolboxes, retaining your lockable tool storage while guarding the remainder of the bed against thieves and inclement weather.

Trifecta Toolbox 2.0 Tonneau Covers can accommodate an 18–20-in. deep crossover toolbox, utilizing the patented L-Channel to bridge the toolbox-to-tonneau gap. When paired with Extang’s exclusive snap-on triple-fin seals, the clamp-on L-channel design promotes streamlined aesthetics and superior weather resistance to keep your valuables clean and dry.

The Extang Trifecta Toolbox 2.0 Tonneau Cover employs the same robust construction as the original Extang Trifecta 2.0, including a sleek leather-grained vinyl tarp, rigid and lightweight aluminum frame, and dual-pivot MaxHinges.

Installing the Extang Trifecta Toolbox 2.0 is quick and easy using the included tool-free clamps. The front-most Jaw-Grip clamp system utilizes a tool-free T-handle to snug the cover against the bed rails and L-channel. At the rear of the cover lies Extang’s EZ-Lock clamps, allowing effortless operation. Opening the Trifecta Toolbox 2.0 Tonneau Cover is just as easy, thanks to its intuitive tri-fold operation—simply loosen the rear EZ-Lock clamps and fold the cover toward the toolbox to access your cargo.

The Extang Trifecta Toolbox 2.0 Tonneau Cover carries a five-year warranty against defective materials or workmanship on all truck bed cover rails, aluminum components, clamps, bows, hardware, and vinyl covering.

This warranty provides coverage against defective materials or workmanship. The warranty is void if the product has been damaged by accident, unreasonable or improper use, neglect, improper service/installation/removal, modifications, acts of God, normal wear and tear or other causes not arising out of defective materials or workmanship. Interference of this product with other installed accessories or trailers is not covered under this warranty. Consequential and incidental damages are not covered under this warranty.


  • Wind whip damage - Tarps must be secured at all points when the vehicle is in motion. An unsecured tarp will flap, resulting in damage to the fabric.
  • Improper cleaning - It is recommended to use the tested and approved Extang Tonno Tonic or clean with soap and water only. Do not use vinyl conditioners that contain silicone (i.e. Armor All) because they will dry out and crack the vinyl over time.
  • Overloading of cargo - Cargo should not touch the tonneau at any point. Protrusions in the tarp will stress the fabric. Cargo may shift while traveling and cause it to push against the fabric or panels and damage it.
  • Driving with panels open or improperly secured on all folding tonneaus - Prior to vehicle operation, clamps must be tightly secured so that clamp lips tightly grip the inner bedside metal surface. Open position: Tonneau must be completely folded and secured with BOTH buckles. Closed position: Tonneau must be completely flat and secured at all 4 clamps.
  • Opening panels without removal of debris on all folding tonneaus - Top of tonneau MUST be free of foreign material including snow and ice before opening panels or severe damage may result.
  • Towing - Do NOT tow your vehicle from the rear with any Extang tonneau cover on your truck.
