Features to know about

Fast Bed Access: Tri-Fold Design with Auto-Latching

When you’re loading up tools, groceries, or gear, nothing beats quick access. The Trifecta ALX folds back in sections so you can open up two-thirds of the bed in seconds. Just lift the rear panel at the tailgate, fold it forward, and you’re ready to haul larger items without taking the cover off. The auto-latching design secures the panels automatically as you close them, so there’s no need to fuss with tailgate clamps or extra steps.

Secure and Simple: Rotary Release Latching System

Getting into your bed shouldn’t feel like a struggle. The Secure Rotary Release Latching System on the Trifecta ALX makes it easy to open the cover while keeping your cargo safe when closed. A quick turn of the release knob at the rear driver’s side unlocks the panels smoothly, giving you access without wrestling with clamps or straps. Once closed, the mechanism locks into place for a snug, secure fit.

Weather Protection That Lasts: Ancona Pebble-Grained Fabric

Rain, dust, and sun can take a toll on your gear and your truck bed. The Trifecta ALX uses heavy-duty Ancona pebble-grained vinyl fabric to block out water, dirt, and UV rays. The adhesive-free perimeter seals help keep moisture out, while the fabric stays flexible and durable through changing weather. It keeps your cargo dry and your bed clean, season after season.

Built to Endure: Aircraft-Grade Aluminum Frame

This cover isn’t just easy to use—it’s made to last. The aircraft-grade, rustproof aluminum frame and bows have a black powder coat finish that resists corrosion and wear. At about 35 lbs, it’s light enough to remove completely when you need a fully open bed but strong enough to stand up to years of everyday use.

Quick Install, No Tools Needed: T-Handle Clamps

You don’t need drills or wrenches to set up the Trifecta ALX. The self-contained design means you can drop it on and secure it with the built-in T-handle clamps at the cab. Once tightened against the bed flanges, the cover sits flush on top of the rails, giving your truck a clean, low-profile look without permanent hardware.

Works great!

Top sags and catches water like a bird bath.
If it was tighter it would be a better top.



by:

First time truck owner, and first time with a bed tonneau cover. Installation went well, but the side rail interferes with the opening of the Ridgeline's in-bed trunk cover. There is very little lateral adjustment on the side rail, and I have it pushed over as far as it can go. Only hits on one side, and it scrapes the rail. Does allow the trunk cover to open fully, but... Called Extang and they said that was to be expected. Would have been good to know ahead of time. Otherwise, satisfied with the build quality and operation (so far).



by:

Fit was perfect for the 2024 Honda Ridgeline with just a minor rubbing of the truck in-bed trunk lid on the side rails when fully opened.

As usual, the eTrailer installation videos were a life-saver and always better than those from the manufacturers. Very clearly shows full installation process with cautions and detail. This, and competitive prices, are the primary reasons for my always buying through eTrailer when my items are available.

  • Recommended Folding Tonneau Cover for 2017 Chevy Silverado 1500
    For a folding tonneau cover for your 2017 Silverado 1500 I recommend the Extang Trifecta ALX Soft Tonneau Bed Cover - Folding - Vinyl. Manufacturers don't make tonneau covers with specific logos so you will need to add it separately. This is vinyl so you can either add a decal or see if a local shop can print onto the cover. You will need one of the following based on your bed length: -Extang Trifecta ALX # EX97AR 5-1/2 Foot Bed -Extang Trifecta ALX # EX47AR 6-1/2 Foot Bed -Extang Trifecta...
