I have a Leer 700 on my RAM for three years now and just the other day one of the ball joints connecting the piston sheared off. So I contacted Leer directly and they were nice enough to send me two new ones in the mail. All I had to do was drill out the old one and install the new one. My cover is working perfectly again.
The hardware and latch mechanisms are only warranted for a year however I got these for free and in only two days. Now that's customer service.
