2008 Gmc Sierra Tonneau Covers

Sometimes the best thing about your truck’s bed can also be the worst. No matter what you’re carrying around back there, it’s open to the elements and prying eyes alike. Carrying a load of expensive gear and need to make a stop at the hardware store on your way? What’s stopping someone from reaching in and snagging your stuff? Well, tonneau covers (aka truck bed covers), give you the best of both worlds. The ability to hide away smaller items, but then to open up the bed to haul bigger stuff when the time comes. If you're not sure where to start, take a look at our Tonneau Cover Buying Guide. Here you can find everything you need to know for choosing the right truck bed cover for your pickup. You can also review our Top 10 Tonneau Covers for 2020.

Not sure which 2008 GMC Sierra Tonneau Covers are right for you? We have over 18756 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:

"overall a great cover the only problem on install was i had to file down one of the latches as it had a mold seam on it and it would not latch correctly. Still a great cover is the tighest cover i ever installed ( just like above pitcure)" —Scott Z from North Syracuse, NY bought an Extang Revolution Tonneau Cover for a 2008 GMC Sierra.

"This is the second FullTilt cover that I have bought for a heavy duty full size GM truck. Both trucks had the optional rack in the beds and the heavy plastic rail covers on the bed sides. Extang lists the cover for the rack system, but I believe the brackets are identical to the regular cover. I had to trim the plastic to mount the front of the tonneau so it would sit better, the extra height on the bed side still causes the front part of the tonneau frame to pull off of the bed when it is closed. I wish they would thicken the foam on the front section so as to seal better. The bolts on the clamps could be 1/4 inch longer to aid in getting them started due to the extra length they have to go with the rail protectors on the bed rails. I did not notch the plastic under the tonneau brackets that run along the inside of the bed. I like the ease of the fulltilt system but was also hoping for the new style quick release latches on the frame over the tail gate. I would not have to hold onto the allen wrench that comes with the cover. A simple pinch bolt with a grooved or slotted head would secure it to the frame." —Edmond B from Harrisville, RI bought an Extang FullTilt Tonneau Cover for a 2008 GMC Sierra.

"The cover is what I expected, but the instructions leave a lot to be desired. When installing on a GMC, the holder only laps the bed by 1/2 inch each side. This should be noted in the instructions. This ovelap means the cover is the support for the holder." —John V from Spring Branch, TX bought a Pace Edwards Roll-Top Tonneau Cover for a 2008 GMC Sierra.

"Received the cover and i had it installed from box to truck in less than 1 minute. So far so good. The winter weather will tell. It appears to be solid and well built. Thank You" —Gerald E from East Aurora, NY bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.

"Received the cover and i had it installed from box to truck in less than 1 minute. So far so good. The winter weather will tell. It appears to be solid and well built. Thank You" —Gerald E from East Aurora, NY bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.

"Economical, easy to install, and best of all it looks and performs great. I highly recommend this tonneau cover." —Steve L from Buffalo, NY bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.

"The Bakflip is a good choice if you need to be able to fold up your hard tonneau cover. On another truck I have the Undercover hard tonneau and it is great but is not as convenient as the Bakflip. The Bakflip works for me on this truck better because I tow a gooseneck trailer." —Matthew E from Harrisonburg, VA bought a BAK BAKFlip G2 Tonneau Cover for a 2008 GMC Sierra.

"I read up on a bunch of covers and felt this one was perfect for me. It came as represented in catalog and also installed as easy as all the reviews said it would. Very satisfied and have had several snow storms since installing it 2 weeks ago." —John E from Flanders, NJ bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2008 GMC Sierra.

"Excellent product for value, very easy to install, and looks great. Arrived in very short time." —Frederick S from Saint Ignace, MI bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.

"The Trifecta cover is a terrific product! It has exceeded all my expectations in looks and functionality. The cover is a snap to install/remove (one man-3 minutes) and looks like an expensive convertible top. There are no adjustments required, no measuring and the spring loaded attaching clamps are a perfect fit right out of the box. I was concerned about water intrusion on my first trip since there was no time to install the tailgate seal before departure. Sure enough, we hit a fierce rainstorm on the way home from the Gulf Coast, but...... there was literally no water leakage into my GMC Sierra Denali pickup after two hours of driving rain. The top rail fit is tight all around and the cover is so easy to fold and unfold by one person. So label me a very happy customer with my new cover and with the AutoAnything order process." —William L from Brownsboro, AL bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.

"I was a little hesitant to buy this cover because of the price.However the concept of a tri fold is what made me decide on this cover. The cover took me about ten minutes to install with no tolls. It is so easy to operate you can fold it and unfold it in seconds. I have owend this cover for several months and have been through several heavy rain storms and the cover never leaked. This cover is worth every penny I spent for it." —Michael S from Trenton, NJ bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.

Supt.

Should have ordered the more heavy duty pair. These are quite thin but do serve their purpose well. View more reviews...

TruXedo TruxSeal Tailgate Seal

Truxedo tailgate seal for the GMC

Seal quality is good, but since it is considered a universal seat. the installation is a pain, and depending on which vehicle you have, you need to remove it and reinstall several times to find the right location to stop air leaks and voids. Cost seems a little high for what you are getting. If I had to do it over again, I would just go to Home Depot or a similar store and get some regular weather stipping and call it good.

Lund Genesis Tailgate Seal

Excellent Seal-Strong Adhesive

Sealed 2020 Sierra new style tail gate 100%. Need NO small pieces added. Excellent product, very strong adhesive. This is an excellent product. BE sure to cut small piece to test and find exact location to seal cracks. Along bed, I applied seal upside down--does not roll. Very pleased. View more reviews...
