Industry's Best Tonneau Warranty

Please find your Tonneau style below for specific warranty information.


Lifetime Frame & Tarp — The Revolution TonnoExpress TonnoTrifecta and eMAX Tonno carry a lifetime warranty against defective materials or workmanship on all tonneau rails, aluminum components, clamps, bows, hardware and vinyl covering. 

Lifetime Frame & 10 Year Tarp — The Classic PlatinumBlackMaxFullTilt and Tuff Tonno carry a lifetime warranty against defective materials or workmanship on all tonneau rails, aluminum components, clamps, bows, hardware. And a 10-year warranty against defective materials or workmanship on the vinyl covering. 

The Solid Fold and EnCore carry a three-year warranty against defective materials or workmanship on all tonneau rails, aluminum components, clamps, bows, hardware.  


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.  


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 — It is 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 tonneau at any point. Protrusions in the tarp will stress the fabric. Cargo may shift while traveling and cause it to push against the fabric or panels and damage it.
Driving with panels open or improperly secured on all folding tonneaus — Prior to vehicle operation, clamps must be tightly secured so that clamp lips tightly grip the inner bedside metal surface. Open position: Tonneau must be completely folded and secured with BOTH buckles. Closed position: Tonneau must be completely flat and secured at all 4 clamps.
Opening panels without removal of debris on all folding tonneaus — Top of tonneau MUST be free of foreign material including snow and ice before opening panels or severe damage may result.
Towing — Do NOT tow your vehicle from the rear with any Extang tonneau cover on your truck. 

The warranty applies to the original consumer/purchaser.  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.

    I like this tonneau cover so far, easy to install but the only complaint i have is getting cover to secure to rails on the sides when installing, probably cause it was cold outside when I installed it. Looks good on my truck which is a deep cherry red.

    Very easy to install, look and fit are great! Good quality USA made product.

    The tonneau was very easy to install using the supplied hardware. It looks really nice and keeps the bed dry.

    This will add another wonderful review for this product. Before buying, I read the others and was somewhat skeptical about the ease of installation and how well it would really fit. To my amazement, it was true. In less than an hour, my son installed it without problems. We then had a torrential downpour, just right for testing how well it protected the contents. That too was as promised. The seal design lets you quickly roll it back to remove things that have slid forward. Great product!!

    Great cover..easy to install, good materials. Owned another tonneau cover for 13 years. This one lots easier to remove or uncover bed. Looks same as other (that is not made anymore). Instuctions were easy to follow. Need no other tools than the one sent with package. Like that it's made in USA

  • This cover is easily and quickly installed. I bought Extang because I used this brand on a previously owned truck. It was very durable! I would definitely recommend this product!

    Easy to install, good fit, looks great. This was actually a replacement for another tonneau by a different manufacturer that I returned because it was defective. I've had Extang's before and have never had a problem with them.

    This is the third xytang peel and seal I have owned. First for a Nissan, second for a Ford and the last for a dodge. Love them all. I have had Velcro and snap type and peel and seal is far superior I my opinion. I will never own anything else.
