Great price, exceptional ProEFX Tri-Fold Tonneau Cover quality

Looking for the most economical, secure and stylish way to cover your truck bed? ProEFX's Tonneau Covers feature a functional tri-fold cover and a great way to protect your cargo while also maintaining superior access to the back of your vehicle. Protect your stuff from inclement weather and unwanted break-ins.

Easy on, easy access, easy off

Adding value to your truck, the tri-fold ProEFX Tonneau Cover's folding function means you also add versatility to your vehicle and your ability to haul a wider variety of items. Because they are easy to open for access you never have to fuss with your Tonneau Cover, and they easily and quickly remove completely when you want absolute freedom from a soft cover (and the light weight means you won't struggle to get it off). And because of their simple, subtle design, they'll add to the look of your vehicle and harmonize with your truck's other accessories nicely.

Improve your gas mileage

Due to an improved aerodynamic design, when installed, this cover will improve your gas mileage. The reason? Simply put, without a tonneau cover, air flows into your truck bed and causes an opposing force. Having a tonneau cover installed means that your truck bed will be covered, causing less drag. The bottom line: this tonneau cover will pay for itself over time in fuel savings.

Clamp-on installation

ProEFX Tonneau Covers come already assembled and mountable to your vehicle immediately. 100% clamp-on with a super snug fit, you won't have to cut, drill or modify your vehicle's body at all to install your new tri-fold cover. And, because it's so easy, you can install it yourself in minutes. Your cover comes with a limited lifetime warranty on the frame and a five year warranty on the vinyl cover.
