Measure Your Truck Bed for a Tonneau Cover

Does your truck have a track system?

If you're looking for a soft tonneau cover that gives you the convenience of a tri-fold and the utility of a roll up, you need an Extang eMAX tonno. These tri-folding truck bed covers are easy to use, add style, are very durable, and unlike any other tri-fold the eMAX gives you full bed use. Extang designs them specifically for each truck to seamlessly hug your truck bed. Just like any other Extang cover they are built to hold up in adverse weather.

The vinyl cover and folding frame of the eMAX comes completely assembled. The eMAX tonno does not require any drilling to install. Simply mount two base rails to the truck bed using a ½" socket and link the cover portion to its base. Extang's patented Speed Klamps quickly fasten underneath your truck bed rails at the rear of the bed to fold it toward the cab. To fold the cover upright, pull a cable to release the patented SecureShut latch and secure the prop rods and straps to hold it open in the upright position.

Made out of heavy-duty vinyl, the Extang eMAX tonno was built to protect your truck bed and everything you need to haul. It adds protection from the wind & rain, plus keeps everything out of the sight of prying eyes. The aluminum frame is very durable as well as lightweight, making it easy to mount and ensuring fast truck bed access.

Easy installation makes adding an Extang eMAX to your truck simple and fast. Featuring the popular tri fold design, the eMAX tonno is sure to be a great addition to Extang's truck bed cover line-up. The sleek and stylish design also improves aerodynamics. This tonneau decreases wind resistance, saving you cash at the pump. The improved appearance, better fuel economy, and added protection are just a few reasons why the Extang eMAX tonno would be a great fit for you!

Manufactured by Extang, a Truck Hero company.

Order Notes

The with or without cargo management, utili-track, or deck rail system options refer to the factory installed rail system designed to hold moveable cargo cleats along the inside of your truck bed.

Limited Lifetime Warranty

WARRANTY DURATION: The Extang eMAX tonno offers a lifetime warranty against defective materials or workmanship on all tonno rails, aluminum components, clamps, bows, hardware, and vinyl. The limited lifetime warranty coverage is as follows: 
WARRANTY CONDITIONS: This warranty is against defective materials or workmanship. The warranty is void if the product has been damaged by accident, unreasonable 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. Consequential and incidental damages are not covered under this warranty.
THE FOLLOWING CONDITIONS WILL ALSO VOID THE WARRANTY: Wind whip damage: Tarps must be secured at all points when vehicle is in motion. An unsecured tarp will flap, resulting in damage to the fabric.
Improper cleaning: Recommended to use the tested and approved Extang Tonno Tonic™ or clean with soap and water only. Do not use vinyl conditioners (i.e. Armor All®) because they will shrink the vinyl.
Overloading of cargo: Cargo should not touch the tonno at any point. Protrusions in the tarp will stress the fabric. Cargo may shift while traveling and cause it to push against the fabric and damage it.
The warranty applies to the original consumer/purchaser and for the truck on which the tonno was originally installed and shall not apply if the product has been removed from the original vehicle.
Warranty registration must be on file and/or proof of original purchase (detailed and dated receipt) required for warranty to be effective. Warranty coverage starts from the date of purchase.
PERFORMANCE: Provided all warranty conditions are met Extang will either repair or replace (at Extang’s option) the product or component. Extang may require the original item to be returned postage prepaid for final determination. Extang reserves the right to substitute and offer the respective warranty discount on an entire replacement system or provide other remedies than those listed in this warranty for discontinued products or other reasons. A return authorization number must be obtained from our customer service department prior to returning any product. Shipping charges will apply for any repair or replacement. This warranty gives you specific legal rights and you may also have other legal rights which vary from state to state.


The Extang eMAX tonno can easily be installed at home with a ½ inch socket with no drilling into the bed. The instructions provided are clear cut and easy to read with a video tutorial available from Extang to reference. Please feel free to contact us at any time if you have any questions or need additional information.
