The Extang Tuff Tonno Tonneau Cover is designed for smooth, sleek looks on your truck. Its new J45 "peel & seal" closure system makes a super flat, tight fit, and the rotating tail rail keeps your tarp perfectly tight. When it's time to haul larger loads, the Tuff Tonneau rolls up and out of the way.

This Extang tonneau cover is designed to your specific year, make, and model truck, for the best fit and flawless looks. Its heavy-duty leather grain black vinyl tarp adds a sophisticated look to your truck that's durable enough to get work done. The J-45 seal is easy to use and keeps the elements out of your bed. The TuffTonno's new LeverLock corners let you attach or remove the tail rail instantly with no tools or screws and hold the tail rail securely in place. The spring-loaded "Monster Bows" are simple to install and remove, and hold strong at any speed and through even the roughest driving conditions. They're also adjustable between two different heights - go with high bows for great water shedding and better gas mileage, or set them to low for sportier looks and cold weather use.

Keep your drill in the toolbox - Extang's own TuffKlamps install to your bed rails in minutes without any cutting, drilling, or damage. Your Extang Tuff Tonneau Tonneau Cover is backed by a 10-Year Warranty on the tarp and comes with a Lifetime Warranty for the frame.

Instructions very clear, measuring to make sure the frame is located properly in relation to the pickup bed takes the most time but not rocket science. For our truck (2017 Chevrolet Silverado) to get the proper height off the bed at the rear of the frame (tailgate end) to clear the tailgate, you will need to request a #2007 foam kit from Extang. Call them, they will send it FREE of charge in about 2 or 3 days. This foam kit shows where additional foam needs to be added to the underside of the frame on both sides.

Install Time: 1-2 hours

Had to call Extang because of some problems. More foam tape needed at the tailgate end to boost the side rails because the tail would not open or close. Plastic corner on tailgate rail had a gap so needed a new tailgate rail. Wrong foam tape on tailgate rail, had same tape as the cab rail, had to be replaced. I have owned two Extang covers before and everything was a one. Extang said they would send the things I needed to correct my problems. They are very good at sending you whatever you may need as I have found in the past.
