The BAKFlip MX4 Tonneau Cover is currently BAK Industries #1 seller and its no wonder why! Its got the security and water-tight features you expect from a truck bed cover and a few new bells and whistles thrown in that arent easily found in todays top tonneau covers.

Made specifically to fit your truck, the BAKFlip MX4 has something that you wont find in many tonneau covers - its triple fin tailgate seal lets you close the MX4 whether your tailgate is open or shut.

Whats more, improved prop rod clips add more stability and security to your truck when you are hauling large loads and need to drive with your tonneau cover open, but still attached. You can drive your truck with the tonneau cover fully or even ⅔ open.

Improved bumper pads on the the A-panel and B-side bumpers provide enhanced durability when your cover is completely open. Improved rails and the included drain tubes ensure that your covered load will remain secure and dry.

Better still, no-drill, clamp-on installation means that you can install the tonneau cover with ease in very little time. A string latch system on both sides of the BAKFlip MX4 Tonneau Cover let you open each section of your cover easily from either side of your truck bed.

Best of all, your BAKFlip MX4 Tonneau Cover is Made in the USA!

Seems like a great solid cover

This cover at first seemed great but at the 2 year mark I'm looking for a new one! The cover itself is built very well but the release bars that are used pretty much every single day are cheap plastic and broke about 6 months ago. The gaskets on every panel have also cracked and leak. Their customer service is very good at Bakflip and they have sent me parts that have fallen off but I believe for the price this unit should last more than 2 years! It may work for someone who doesn't use it on a daily basis.

I really enjoy my new bakflip mx4 bed cover. Had a couple of screws missing and a damaged rail. Customer support team were fantastic and professional. They sent me a new set of screws and rail to replace the missing/damage part immediately. I highly recommend this product. Thanks
