Features
- One-Hand Rotary Release: Drop the tailgate, twist the rotary knob on the driver side and lift: the rear panel opens with one hand. Extang says this release is unique among soft tri-fold covers.
- Latches Itself When Closed: Lower the cover onto the bed and the Auto Latching System catches both latches on its own, so there are no tailgate clamps to set every time you close it.
- Folds for 2/3 Bed Access: Fold the cover toward the cab and fasten both buckle straps for about two thirds of the bed. When a load needs every inch, the whole cover comes off in minutes.
- Hand-Tightened Clamps: T-handle clamps hold the cover to the bed rails at the cab. They tighten by hand with no drilling, and loosen the same way when you want the cover off.
- Pebble-Grain DualShield Vinyl: The top is Extang's 50-grade DualShield vinyl, made in two layers with a pebble-grain finish. It is built for long service.
- MegaBows and Dual-Pivot Hinges: Heavy-duty aluminum MegaBows and dual-pivot hinges support the vinyl so rain, hail and snow are less likely to make it sag, and Extang says they reduce wear over time.
Description & Fitment
The Extang Trifecta ALX Soft Folding Tonneau Cover (90470) fits the 2014-2021 Toyota Tundra with the 8' bed. It is a soft tri-fold cover with pebble-grain DualShield vinyl and a one-hand rotary release that latches itself when closed. Heavy-duty aluminum MegaBows and dual-pivot hinges support the top, and it folds toward the cab for two thirds of the bed. Hand-tightened clamps hold it in place, and it is not for trucks with the factory deck rail system.
Fitment & Compatibility
| Years | Model | Bed | Notes |

| 2014-2021 | Tundra | 8' | without Deck Rail System |
Check your bed: measure inside the bed floor from the bulkhead to the inside of the closed tailgate. Extang lists this bed as 8'. This version is for trucks without the factory deck rail system.
Not for: the 2014-2021 Toyota Tundra 6'7" bed (90465). That is a separate Trifecta ALX part.
About Extang
Extang is based in Ann Arbor, Michigan. Extang publishes a truck-specific install sheet for each Trifecta ALX version and backs the cover with a limited lifetime warranty.
The Trifecta ALX is Extang's soft tri-fold with the ALX rotary latch, the same one-hand latch used on the hard Solid Fold ALX and the low-profile Endure ALX.
Warranty note. Extang's limited lifetime warranty applies to the original purchaser, with warranty registration on file or a detailed, dated receipt. Keep your order confirmation from us, and contact us for warranty claims and registration help.
Frequently Asked Questions
Will this fit my 2014-2021 Toyota Tundra?
Yes, if it has the 8' bed, without the factory deck rail system. Measure inside the bed floor from the bulkhead to the inside of the closed tailgate and compare it with the 8' label. If yours is different, look at the 2014-2021 Toyota Tundra 6'7" bed (90465). Not sure? Send us your VIN and we'll confirm.
Does it matter if my Toyota has the deck rail system?
Yes. This version is for beds without the factory deck rail system.
How is the Trifecta ALX different from the Trifecta 2.0?
Both are soft tri-fold covers on an aluminum frame. The Trifecta 2.0 is held shut at the tailgate by spring-loaded EZ-Lock clamps that you release by hand. The ALX replaces those with a rotary knob you turn with one hand to open it, and latches that catch on their own when you close it.
Will it keep rain and snow out of the bed?
It is built to. Extang says the triple-fin seals are part of the frame rather than glued on, and the MegaBows keep the top from sagging under rain, hail and snow. Like any soft folding cover it is weather-resistant rather than watertight. Brush snow and ice off before you fold it; Extang's warranty requires that.
Can I drive with it folded open, or take it off?
Yes to both. Fold it toward the cab and fasten both buckle straps with the tethers attached, and you can drive with about two thirds of the bed open. For the whole bed, loosen the clamps by hand and lift the cover off. Never drive with it partly open.
How do I clean the vinyl?
Use Extang Tonno Tonic or mild soap and water. Skip vinyl conditioners that contain silicone or petroleum: they dry the vinyl out, and Extang's warranty excludes damage from them.
Installation
- Torx wrenches
- Hex key come in the box
