I recently noticed the rubber across the last panel of my MX4 Bak flip cover (closest to the tailgate) was starting to split across the panel (underside). I contacted customer service inquiring if it was still under warranty and if it would be possible to have the last panel replaced. I'm less than 2 months away from the 5 year warranty expiring. To my surprise they replied back informing me the MX4 cover has been redesigned and they will be shipping a new replacement which will come with a new cover, rails and hardware. I love when a company stands behind their products.
