Key Features

Hard tri-fold cover for the 2014-2021 Tundra 5'7" bed WITH deck rail system
1-inch EnduraShield TPO panels resist dents, scratches, and UV
Up to 600 lb evenly distributed load rating
Secure Rotary Release latch: drop tailgate, twist, and lift one-handed
Tool-free Jaw-Grip clamp install, removable in seconds for full bed access
Textured-black EnduraCoat aluminum frame for a low-profile look
With-rail fit distinct from the no-rail sibling 88460

The Extang Solid Fold ALX (MPN 88461) is a hard folding tonneau cover for the 2014-2021 Toyota Tundra 5'7" (66.7") bed equipped WITH the factory deck rail system. This is the with-rail configuration, mounted with clamps sized to work alongside the OE rails; the no-rail version of the same cover is the sibling 88460.

The Solid Fold ALX is built around rugged 1-inch-thick EnduraShield TPO panels over an aircraft-grade aluminum frame with a textured-black EnduraCoat finish. The panels shrug off dents, scratches, and UV fading while supporting up to 600 lb of evenly distributed weight. A Secure Rotary Release latching system offers one-handed operation: drop the tailgate, twist, and lift, and the cover automatically latches when closed against the bed rails.

Bed Length

Cut specifically for the Toyota Tundra 5'7" (66.7") bed. Bed length is the primary tonneau fitment axis, so confirm your Tundra has the short bed.

Deck Rail System

This is the WITH-deck-rail version. If your 2014-2021 Tundra does NOT have the deck rail system, order the sibling Extang Solid Fold ALX 88460 instead. This cover will NOT work with the Trail Special Edition bed-mounted storage boxes.

What's Included

Solid Fold ALX folding cover
Jaw-Grip clamps and rotary latch strikers
Installation hardware and instructions

Fitment

Fits the 2014-2021 Toyota Tundra 5'7" bed WITH the deck rail system. Does not fit Tundras without the deck rail (use 88460), does not fit the 6'6" or 8'1" beds, and does not fit the 2022-and-newer third-generation Tundra (use 88472).

FAQ

Does the Extang 88461 fit with or without the deck rail system?

The 88461 is the WITH deck rail system version. For a 2014-2021 Tundra 5'7" bed without the deck rail, order the sibling 88460.

Is the 88461 the Solid Fold ALX or the Solid Fold 2.0?

It is the Solid Fold ALX, Extang's aluminum-framed EnduraShield TPO cover. The older 2.0 line uses different part numbers (for example 83460/83461).

Which bed length does the 88461 fit?

It fits the 5'7" (66.7") short bed only.

How much weight can the Solid Fold ALX hold?

It is rated for up to 600 lb of evenly distributed weight when closed.
