Extang Solid Fold ALX Hard Folding Tonneau Cover for 2020-2026 Chevrolet Silverado 2500/3500 / GMC Sierra 2500/3500 (8' Bed)

The Extang Solid Fold ALX is a hard folding tonneau cover for owners who want a covered bed most days and an open one when the load is awkward. Its 1 inch thick EnduraShield TPO panels fold toward the cab on dual-pivot MaxHinges to clear roughly two thirds of the bed, and the whole cover lifts off in seconds when you need all of it. Snap-on triple-fin seals keep water out and the cover carries up to 600 lb spread evenly. The ALX difference is the Secure Rotary Release: drop the tailgate, twist and lift with one hand. Part number 88658 is the 8' bed application for the 2020-2026 Chevrolet Silverado 2500/3500 / GMC Sierra 2500/3500.

What's Included:

• Solid Fold ALX hard folding tonneau cover with EnduraShield TPO panels
• Tool-free Jaw-Grip front clamps
• Bolt-on rotary latch strikers
• Hardware kit
• Install guide

Features

Triple-Fin Seals Around the Perimeter
Snap-on triple-fin seals run the full perimeter of the cover, hinge caps close the joints between panels and hard polymer rubber corners fill the spots where water usually finds a way in. Together they keep rain and road spray off your cargo.

Twist and Lift, One Hand
The Secure Rotary Release system is what sets the ALX apart from the Solid Fold 2.0. Lower the tailgate, twist the release and lift the panel with one hand. Fold the cover back down and it latches itself against the bed rails.

Inch-Thick Panels, 600 lb Cover Rating
Each panel is a full inch of EnduraShield TPO, which resists dents, scratches and UV fading. The panels ride on an aircraft-grade aluminum frame with a textured EnduraCoat finish, and the cover supports up to 600 lb of evenly distributed weight.

Two Thirds Open, Strapped Down
Dual-pivot MaxHinges let the panels fold toward the cab, leaving roughly two thirds of the bed clear for taller cargo. Integrated buckle straps hold the folded stack in place so you can drive with the cover open, once both buckles are fastened.

Off the Truck in Seconds
Tool-free Jaw-Grip clamps hold the front of the cover to the bed rails. When a load needs the whole bed, release the clamps and lift the cover off without reaching for a tool. Extang puts the whole job at a matter of seconds.

Clamps On in Under an Hour
Installation is a Level 1 job needing only ordinary hand tools. The Jaw-Grip clamps grab the front bed rails without tools and the rotary latch strikers bolt on at the rear. Nothing is cut, drilled or modified and all the hardware is included.

Warranty, Shipping & Returns

Warranty. Extang covers the Solid Fold ALX with a 5-year limited warranty against defects in materials and workmanship on the rails, aluminum parts, clamps, bows and hardware, for the original purchaser with proof of purchase. Extang will repair or replace the part at its own option. Damage from accidents, misuse, improper installation, modification or normal wear is not covered, nor is interference with other accessories or trailers. Driving with the panels unsecured, opening the cover with snow or ice on it, letting cargo press against the panels, cleaning with silicone conditioners or towing the truck from the rear will all void it.

Free shipping. This item ships free to the lower 48 states. Because it is an oversized item, it ships by freight or oversized parcel and typically arrives in 3 to 7 business days.

Inspect on delivery. Please inspect the packaging before signing. If you see any damage, note it on the delivery receipt and contact us right away, and we will make it right.

Returns. Unused items in their original packaging can be returned within 30 days of delivery. If an item arrives damaged, defective or wrong, return shipping is on us. See our Returns & Refunds Policy, or email support@prestigetruck.com with any question.

About Extang

Extang is a truck bed cover manufacturer that puts its own name on the parts that matter: proprietary EnduraShield TPO panels, the EnduraCoat aluminum finish, dual-pivot MaxHinges and the tool-free Jaw-Grip clamp. The Solid Fold ALX itself is assembled in Michigan and Extang lists it as made in America.

Alongside this cover Extang lists the closely related Solid Fold 2.0, the low-profile Endure ALX, the soft-folding Trifecta ALX and the Solid Fold Toolbox 2.0. The Endure ALX and the Trifecta ALX use the same one-hand rotary latch that the Solid Fold ALX has.

The Solid Fold ALX carries a 5-year limited warranty on rails, aluminum parts, clamps, bows and hardware. Extang's care rules are simple: wash with soap and water or its own Tonno Tonic cleaner, skip silicone conditioners, clear snow and ice before folding and never let cargo push against the panels. Install sheets are truck specific.
