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.

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

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 — 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.

  • A few issues, but overall excellent!

    The trifecta is perfect in overall design. However, I had 2 adjustments I needed to account for after receiving it. 1. Toolbox height. I had a Home Depot Husky Low Profile box, meaning the handles were below/parallel to the actual cover once in place. It was easy to fix on my end, the box was still new and I could swap it back out at Home Depot with another box where the handles and height of the top of the box were well over the cover. 2. The main cover support battings that make up the frame across the truck bed, needed to be slid up a bit in order to accommodate my Sierra. It was easily done by unscrewing the self tapping screws and then sliding the batting forward an inch and a half to make sure the quick releases we\\\'re in a more secure part of the bed rail vs. just hooking onto the plastic part of the bedrail closer to the tailgate. But, overall it\\\'s fabulous, very light weight and easy to take on and off. It\\\'s doing the job and I couldn\\\'t be more pleased. My only suggestion is make sure you have a tool box high enough up and really take the time to find the best placement for those battings to find a solid secured position.
